Abstract

 In this paper, a new type of gas-to-gas heat exchanger that operates based on energy conversion between gas enthalpy and thermal radiation is developed. This system consists of one high temperature section and two recovery sections. In high temperature section, the enthalpy of hot gas flow converts to thermal radiation by porous layer in this section and the reverse direction of this process occurs in recovery sections. A theoretical analysis is conducted for the one-dimensional system where convection and radiation take place simultaneously in three porous layers. In order to obtain the thermal characteristics of this type of heat exchanger, the coupled energy equations for the gas and porous mediums based on two-flux radiation model are solved numerically using iterative method. Computational results show that this type of heat exchanger works effectively especially when the porous layers with large optical thicknesses and small scattering factors are used in the system. In order to validate the numerical results, a comparison between theory and experiment is made for a system of heat recovery and a good agreement is found.
