Building Energy Efficient Products for a Better Tomorrow Using CFD. The world is badly in a need of products that are energy efficient, as global energy consumption levels increase at an alarming rate.
It is the only reason why government agencies and manufacturing organizations are strained to look for possible alternatives that consume less energy. In such an aggressive environment where government regulations and customer requirements are both focused on utilizing the energy efficiently, modern technology is proving to be extremely beneficial. The use of computer aided simulations have made it possible for engineers and researchers to visualize and figure out possible alternatives of the product designs for the sake of saving the energy consumption.
In our everyday life, we utilize energy through different means, which is exactly where the use of simulation tools such as Computational Fluid Dynamics (CFD) becomes practically useful.

Multiphase flow analysis its Common Uses and Applications. Simulation Explains How A Sneezing Person in an Airplane Can Make You Sick. One of the leading commercially available simulation software from ANSYS helps in determining the fluid flow behavior for various engineering applications.
Engineers utilize these simulation tools to optimize aircraft wings for optimum lift and drag in the air, or improve the performance by reducing aircraft weight. However, the ability to predict the air flow through aerodynamic analysis is also helpful in determining the spread of flu in a contained space. A recent video posted by Popular Science in collaboration with ANSYS, reveals one such simulation performed for a typical aircraft cabin and shows why it is better to sit far away from a passenger who is sick and sneezing. The video shows how influenza particles can travel in a pressurized airplane cabin performed using simulation software from ANSYS.
The colored particles are meant to show how the stuff spreads inside the cabin. The flu is an airborne pathogen and you can easily catch it when one sneezes. About Author: Controlling Pressure Drop in Industrial Valves Using CFD. The Need to Revolutionize CFD Capabilities for Future Aircraft Simulations. Computational fluid dynamics (CFD) has remained a vital tool for aircraft design assessment ever since its inception.
Its use has already brought a paradigm shift in the aircraft design process. Jan 6, 2015 -- However, since past decade, the advancements in this technology has reached a stagnation point as RANS methods have become a high-fidelity method of choice as it permits the use of large meshes, complex geometries and more number of runs. Benefits of Using Virtual Wind Tunnels for Aerodynamic Studies.
Wind tunnels have been one of the prominent testing tools for aerodynamic investigations.
However, its use is limited mainly due to the cost required in physical setup. Additionally, these tests are time consuming and stretched the product design cycle considerably. Fortunately, use of computational tools such as CFD provides a solution against the problems associated with physical wind tunnel tests. Despite the ability to assess aerodynamic forces and air flow characteristics more quickly, these tools are known to consume considerable time in selecting the boundary conditions, applying flow physics and generating mesh over the CAD geometry. Virtual Wind Tunnel Design Thankfully, in order to fasten the process, recent development in CFD tools have made possible to perform aerodynamic analysis even more easily through virtual wind tunnel software.
Contrary to physical setup, in virtual wind tunnels, adjusting wind conditions requires merely a touch of a button. CFD Simulations to Save Lives. The potential of CFD simulations is increasingly being exploited in many modern engineering fields.
However, the use of CFD techniques is more restricted to manufacturing domains, to study and optimize the performance of equipments and systems involving fluid flows. Yet, recent advancements in scanning and computing technologies have opened a whole new set of opportunities in biomedical engineering field. The complexity of human anatomy and human fluid behavior is a reason why CFD techniques took a little more time to be utilized as a research tool in medical domain.
Medical researchers, now have the ability to gain knowledge of how body fluids and system components are expected to perform, making possible to improve the bio-fluid physiology studies and design better medical treatments and devices. How CFD Analysis Aids Mechanical Engineers In Problem Identification And Mitigation. CFD Simulation for Exhaust Gas Dispersion to Control Industrial Emissions. Exhaust gas streams emitting from industrial process plants consist of harmful pollutants, which are carried away for sufficiently large distances from the source.
The control of these pollutants dispersion is mandatory to avoid spreading of toxic gases into urban areas nearer to plant locations. There are several regulations issued by government and environment protection agencies that define the pollutant concentration limits in the ambient air or in gaseous emissions. As such, predicting the exhaust gas dispersion into atmosphere is essentially required in order to tune the equipments and exhaust systems, so that the pollutant concentrations remain at an acceptable level.
Combating Heat in Automobiles Using Computational Fluid Dynamics. Posted by: Mehul Patel | Posted on: December 16th, 2014 Automobiles are largely composed of components that directly or indirectly possess relationship with heat transfer. Although heat is essentially required to churn out power from the engine, rest of the components are being incorporated to accommodate or transfer the generated heat, once it completes the job of producing necessary power. The efficiency of the automobile is largely dependent on successful utilization as well as evacuation of the heat from different components apart from the engine. Once the heat becomes uncontrollable, the components can get damaged and affect the overall performance.
An overheated engine would eventually seize and stop generating power, requiring an effective cooling system. Predicting Cavitation in Centrifugal Pumps through CFD. Cavitation is a widely known problem associated with pumps, causing severe impact in overall performance as well as malfunctioning due to improper pump inlet conditions. As such, it is highly important for a pump user to know what cavitation is, its effects and possible ways of controlling it using modern simulation techniques such as CFD. The use of CFD permit incorporating design changes in the early development phase of the product, thereby considerably reducing the time-to-market. The Cavitation Phenomenon: Cavitation can be defined as a process of generation and destruction of the vapor phase of a liquid subjected to low and high pressures simultaneously at constant ambient temperatures. It is a thermodynamic change of state with mass transfer from liquid to vapor and vice versa, i.e. bubble formation and collapse.
Optimizing Designs of Industrial Pipes, Ducts and Manifolds Using CFD. Almost every industry involves the utilization of pipes, ducts and manifolds to handle wide range of fluids, gases or a mixture of solids and fluids. It is evident that these transport mediums are exposed to critical pressure and temperature, requiring thorough study on their designs to ensure longevity and performance. A theoretical design calculation for these equipments only give information about the inlet and outlet conditions, and does not involve the details on the fluid flow behavior that is actually occurring inside the channels. Since the design of these components play important role in determining losses in desired output pressure, temperature or flow rate, it is essential to conduct comprehensive analysis of the system. Computational fluid dynamics proves to be a decisive tool for such cases, providing detailed insights about important design considerations that can be incorporated prior to actual application.

Due to its simplicity in construction, ejector is widely being used in applications such as extraction, compression, ventilation and air conditioning, uniform mixing of two streams and propulsion or lifting.
Although being a small component, jet ejectors play a crucial role in industrial steam jet refrigeration systems. Its purpose is to increase the motive steam pressure through convergent-divergent geometry, and also allow the entrainment of secondary steam to promote regeneration. The efficiency of the refrigeration system is fairly dependent on the ejector performance, despite having no movable parts. As such, ejectors are required to be designed according to the required refrigeration application. Its efficiency however relies on several geometrical factors, such as nozzle diameter and angle, throat and diffuser length.
