I am working on Magnetic cooling system, where for the solid domain, I have to invoke an additional variable source term (magnetocaloric energy) in the energy equation. How can I do that?
Dear Prakash Singh ,
Please check this Wikipedia page:
https://en.wikipedia.org/wiki/Magnetic_refrigeration
you might need to use a modified form of ΔTad integral by defining the derivative of magnetization of the refrigerant.

Thank you for reply Malika Zaim ma'am.
I had already tried the equation (1.19) of the page no 7 from the book Magnetocaloric Energy Conversion: From Theory to Applications. I had taken T_1 = 298 and B_1 = 0, then calculated the value of S_1=S. Then after fixed the value of B_2 =2, and calculated the temperature T_2 such that S_2 becomes S or near to S. But I am not able to get the accurate result.
I Used C program for whole calculations.
S_1(0, 298)=S_2(2, T_2), DelT_ad=T_2 - 298.
Please suggest If I am doing something wrong.
Thank you for the reply, sir Mohammad Afkani .
How can I do that with C program? I had already tried but not able to validate it.
Please suggest something, sir.
Dear Prakash Singh ,
It depends on your system properties, is M, the magnetization of the refrigerant, a function of temperature or/and external magnetic field or no? if yes, do you know the relation? so you can apply numerical derivative and integral. here is a manual that helps you do that using the C programming language.

let me know if I can help any further.
Cheers.
