Likewise, the heat flux through undirected microgeometry is inhibited. However, these structures generally have very high pressure drops due to their undirected microgeometry. Examples of a stochastic topology include metal foams and packed beds. The cellular metal structures can be classified into two broad classes: one with a stochastic topology and the other with a periodic structure. Engine cooling in the transport sector or heating, cooling, and air conditioning systems in buildings are two example applications. ![]() ![]() These structures are attractive for a wide range of applications where dissipation of heat over relatively small spaces is demanded. ![]() In recent years, the development of cellular metal structures as heat transfer surface area enhancements has been intensified.
