Computational Modelling and Simulation of Polymer Electrolyte Membrane Fuel Cell with COMSOL

Çakmak, Mehmet Ekrem; Sorgulu, Fatih;

In this study a two-dimensional computational model of a polymer electrolyte fuel cell (PEMFC) was adopted from previous studies and simulated using COMSOL MP v5.2 in order to have a starting point for developing a better representative PEMFC model. Navier-Stokes, Brinkman, Maxwell-Stefan, and Butler-Volmer equations were solved to calculate the flow in the gas channels, the flow in porous layers, the mass transport (diffusion of species), and the current distribution in the model, respectively. The polarization curve was plotted and compare...

Simulation-Optimization of a Patented Baffle Design with Parallel Computing on TRUBA

Kuzay, Mustafa; Nasyrlayev, Nazhmiddin; Demirel, Ender;

Treatment of surface waters in large cities has been emerged as a critical point of interest for governments in recent years with increasing clean water demand and development of energy intensive water treatment technologies such as ozone and ultraviolet. Raw water is mixed with the disinfectant in a multi-chambered contact tank at the last stage of the treatment procedure to remove viruses and pathogens from the water. An efficient contact system is required for the effective disinfection of water with less disinfectant and energy usage, wh...

Large-eddy simulation of submerged hydraulic jump using OpenFoam

Demirel, Ender;

Large-eddy simulation of submerged hydraulic jump is performed for the Froude number Fr=4.24 and submergence ratio S=0.67 using open source CFD code OpenFoam. Numerical simulation is carried out using parallel computing strategies on TRUBA (Turkish National Science e-Infrastructure) High Performance Computing Center (HPC). A novel boundary condition is developed to impose a developed turbulent velocity field at the inlet. The proposed boundary condition developed on OpenFoam 4.1 libraries can automatically adjust inlet water depth and v...
