Energy2D - Interactive Heat Transfer Simulations for Everyone. “Please accept our thanks and congratulations for your very interesting work which I am sure are having a great positive impact in our society.” — from Roberto Quevedo, Instituto Volcanológico de Canarias, INVOLCAN, Puerto de la Cruz, Tenerife, Canary Islands, Spain By Carmen Trudell, University of Virginia What is it?
Based on computational physics, Energy2D is an interactive multiphysics simulation program that models all three modes of heat transfer—conduction, convection, and radiation, and their coupling with particle dynamics. Energy2D runs quickly on most computers and eliminates the switches among preprocessors, solvers, and postprocessors typically needed to perform computational fluid dynamics simulations. It allows you to design "computational experiments" to test a scientific hypothesis or solve an engineering problem without resorting to complex mathematics. Finding a temperature rise in a resistor. HELP! I'm just a Neanderthal electrical engineer and i know about blackbody radiation, but i do not think that this approach is the correct one. if the furnace element is perfectly insulated from ambiance, then when you turn it on, energy continues to flow into but no energy flows out (unless you mean the E&M radiation itself, but then it is not assumed that it's perfectly insulated). the rate of energy being conducted from the furnace core is proportional to the temperature difference of the core to the ambient. as long as the (electrical) power in exceeds the power lost, the core will continue to increase in temperature until there is an equilibrium when the temperature difference is large enough that the net power is zero or the power in is equal to the power lost. this depends on lots of details, like how well is the core isolated from the ambient. if it were perfectly insulated and you had non-stop power applied, the upper bound of the temperature of the element is unbounded. r b-j.
