Abstract Various models for predicting the flow and heat transfer in a porous cryocooler regenerator have been proposed in the literature. One such model utilizes a semi-implicit set of equations after making some simplifying assumptions, resulting in a momentum equation that is decoupled from the energy and continuity equations. This work addresses concerns with a semi-implicit model based on scale analysis. An important result is that the pressure gradient term in the energy equation, which has been neglected in the semi-implicit model, is leading order.
