Numerical study of thermomagnetic cycle

We estimate the efficiency and power of a thermal energy harvesting thermodynamic cycle using magnetocaloric material as active substance. An accurate model of material, based on measurement, or theoretical are used to simulate a thermodynamic cycle and foresee magnetic work and then compare it to the maximum work. Afterwards power is estimated using a simple thermal exchange model. Simulations of different cycles for different working points illustrate the tradeoff between power and efficiency.
