Study of a micro-structured PHE for the thermal management of a fuel cell

Abstract

In the constantly growing market of fuel cells, the heat management of the system is a crucial area of research, since it affects the efficiency, operability and lifetime of the fuel cell. The CFD simulations performed for a plate heat exchanger (PHE) with flat plates clearly demonstrate temperature non-uniformity across the membrane of the unit cell. The CFD code was successfully validated with experimental data acquired from a setup that reproduces the geometry and simulates the thermal behaviour of a typical unit PEMFC. Additionally, the performance of a novel PHE, with micro-structured corrugations on its plates, was studied with the previously validated CFD code. The results clearly show that the proposed plate modifications can increase temperature uniformity across the membrane more than 20% compared to that of the flat plate.

Computational Modelling for Efficient Transdentinal Drug Delivery

“…Employing the Design Exploration features of ANSYS Workbench ® package and following the Design of Experiments (DOE) methodology, a set of "computational experiments" has been initially designed. The DOE methods allow the designer to extract as much information as possible from a limited number of test cases and makes the method ideal for CFD models that are significantly time-consuming [31]. A summary of the design variable ranges is given in Table 1.…”

Computational Modelling for Efficient Transdentinal Drug Delivery

“…Employing the Design Exploration features of the ANSYS Workbench ® package (18, ANSYS, Canonsburg, PA, USA) and following the Design of Experiments (DOE) methodology, a set of "computational experiments" was initially designed. The DOE methods allow the designer to extract as much information as possible from a limited number of test cases and makes the method ideal for CFD models that are significantly time-consuming [32]. Eventually, the temporal and spatial concentration at the pulpal side of the disc will be calculated using the computational procedure.…”
