Transport Phenomena in Fluid Dynamics: Matrix Heat Exchangers and Their Applications in Energy Systems

Abstract

Heat exchangers play an important role in maintaining the operating temperatures required for high thermal performance of energy systems. Energy systems such as heat pumps, electric generators, water heating and steam generation, conversion chemical processes, and heat dissipation equipment are parts of the deployed equipment. The fact that heat transfer intensifies by increasing the surface area of contact between the working fluid streams and the added benefit of near elimination of axial heat transfer gives the Matrix Heat Exchanger (MHE) an edge over many other compact heat exchangers concepts. MHE consists of a stack of alternating perforated plate-spacer pairs which are bonded together to form leak free passages for the fluid streams. This effort explored the possibility of using MHE as steam generator and established a model to estimate the heat transfer coefficient and the flow friction coefficient in case of two phase flow in MHE.
