Harmonic analysis of temperature profiles of active caloric regenerators

The design of a thermal regenerator is initially carried out by considering the fundamental influencing variables. For novel solid-state cooling systems using active caloric regenerators, non-linearity coupled phenomena material properties, heat transfer, and hydraulic flow can complicate interpretation experimental simulated results. Based on boundary conditions sinusoidal magnetic field fluid flow, we elucidate operation regenerators deriving easy-to-manage analytical expressions for temperature transients materials transfer fluid. An internal measurement system with an estimated uncertainty ±0.3 K packed bed has been developed validation. derived have acceptable accuracy relative to numerical results profiles in both magnitude sensitivity, where average maximum errors are ?10% ?15%, respectively. Useful figures merit post-calculated profiles. We found that linear passive nonlinear their functions configuration operating parameters.
