![]() ![]() Often you can approximate the heat capacity of a solid with a constant, but the way heat spreads through a solid is not easily calculated in closed form. use a simulation program such as Comsol to build a model (but you might still want to confirm it is correct).Ī simulation can tell you temperatures that are hard to physically measure and it can also tell you what happens dynamically- how quickly the temperature changes.make a bunch of simplifying assumptions and attempt an approximation.If you have a more complex situation you have a few options Convection and radiation are very nonlinear, are temperature dependent and geometry comes into it- such as laminar flow and turbulence.įor simple things like insulated wires operating close to room temperature you can look up the temperature rise for typical simple situations (still air, some different numbers of them bundled etc) but the answers will be approximate and probably based on experiments someone did many decades ago. ![]() The eventual temperature it reaches depends on a couple obvious things - the power dissipated and the ambient temperature, and a bunch of other things- the geometry, the actual temperatures and intermediate materials such as air (heat transfer is via several different modes such as conduction, convection and radiation- sometimes you can ignore one or the other, but it changes depending on temperatures and temperature differences and geometries). "What i need to know is let say at 5 volt 10 amps what gonna be temperature on a conductive material in celsius (sic)"
