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 ...

In this study, the response surface methodology (RSM) has been applied to optimize the operating conditions of direct methanol fuel cell (DMFC). A quadratic model was developed through RSM in terms of related independent ...

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 ...

In this investigation, thermal and structural finite element analysis has been employed to analyse the level of stresses developed in Al2O3-spherical cast iron (SG), ZrO2-(12% Si + Al) and ZrO2-SG coatings subjected to ...

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 ...

The convective heat transfer characteristics in a periodic converging-diverging heat exchanger channel are investigated experimentally. Experiments were performed for Prandtl number 0.7, for corrugation angle of 30 degrees. ...

The convective heat transfer characteristics for a periodic wavy channel have been investigated experimentally and numerically. Finite volume method was used in numerical study. Experiment results are used for validation ...

Although ceramic materials are widely selected in the design of components for high engineering applications, the manufacture of ceramic components is quite different to that of metallic or polymer materials. The original ...
