Abstract: Over the last several decades, several factors have contributed to a major transformation in heat pipe science and technology applications. The first major contribution was the development and ...

Abstract: A two-dimensional, steady state, nonisothermal, nonequilibrium, multifluid, two-phase flow model is employed to investigate fuel delivery characteristics, as well as the strong relation between water ...

Abstract: The porous diffusion medium (DM) used in fuel cells has a complex heterogeneous structure in which both hydrophilic and hydrophobic pores coexist. The capillary flow in such a mixed-wet DM is ...

Abstract: The thermal and start-up characteristics of a passive direct methanol fuel cell system are simulated using a numerical model. The model captures both the thermal characteristics of the fuel ...

Abstract: In order to take full advantage of the high energy density available in methanol fuel, one must use high concentration methanol in direct methanol fuel cells (DMFCs). However, this causes ...
