The classical Lattice Boltzmann Method is based on an orthogonal, equidistant lattice structure. Thus, representation of non-rectangular boundaries deserves further attention. Besides the straightforward possibility of ...

In a conventional internal combustion engine, approximately one-third of total fuel input energy is converted to useful work. Since the working gas in a practical engine cycle is not exhausted at ambient temperature, a ...

One of the design parameters of fuel cell is GDL (gas diffusion layer) porosity which helps to remove the water produced and accumulated in the catalyst layers toward the flow channels. In this study, a three-dimensional, ...

In this study, a three-dimensional, single-phase model has been established to investigate the performance of proton exchange membrane fuel cell (PEMFC) with serpentine flow fields. The model was operated in the temperature ...

Fuel cells can be used to provide power for most electrical or electronic devices designed for operation from batteries or from conventional utility power sources. In this study, a three dimensional Computational Fluid ...

The characteristics of convective heat transfer and friction factor for periodic corrugated channels are investigated numerically. In the numerical study, the finite volume method (FVM) is used. Three different Reynolds ...

Water and heat management are the most critical issues for the performance of proton exchange membrane (PEM) fuel cells. They can be provided by keeping hydrogen flow rate, oxygen flow rate, cell temperature and humidification ...
