How to model a rotating heat source in Simulink?

I need help in modeling a rotating heat source in Simulink? This applies to study of a process in which an arc drawn and is impelled to rotate around a surface to cause its heating. Thanks for any help extended to initiate this study with a simulink model

Do you have any equations for how to model your heat source and its effect on your system as a function of rotation angle, rotation speed, distance between the source and the system? Anything? Have you gone through the Simulink onramp training to understand how Simulink works?

[Mukti Chaturvedi]

The heat source has to be modeled as giving the input heat energy = voltage*current/velocity of the moving arc

E=V*I/velocity

Further, heat transfer happens through the 3 mechanisms of conduction, radiation, convection. but for initial model, only the heat input by the source moving at certain velocity is to be considered.

THnaks for any help/directions that you can give regarding modelling of this moving arc source.

yes, I have taken the Simulink onramp training.

Hi @Mukti Chaturvedi

To model a process (rotating heat source) in Simulink, you need a mathematical equation and some parameters to describe that.

If the voltage, currect, and the angular velocity at constants, then you can compute the constant heat energy manually and use a Step block / Constant block as the input.
