“…The meshed model consists of tetrahedral elements predominantly with few hex mesh prism layers adjacent to the interfaces. The generated mesh is comparable to the mesh generated for shell and tube heat exchanger analysis by Cruz et al 15 The mesh was created using a face sizing option with volume influence enabled for up to five layers to capture the flow field near the boundary with reasonable accuracy. For 0.8 million nodes case, only the solid copper coil and the inner fluid zones are meshed with maximum refinement to compute the heat transfer properties accurately.…”

The work presented in this article deals with the reduction of air pollution generated by automobiles. It is accomplished through the process of condensation using novel techniques such as utilization of porous metal foams. A modified geometry dump diffuser is used to facilitate flow of exhaust gases slowly around copper coils thereby condensing them. The condensed gases can be collected and stored in a chamber and then can be carried to industries for recycling. This article involves design of the modified geometry dump diffuser using CATIA V5 tool. The computational fluid dynamics (CFD) analysis of the model is carried out using the ANSYS Fluent software. The inlet parameters are obtained as per the exhaust characteristics of a typical 0.8 l 3-cylinder Gasoline Engine. The results are presented for modified geometry dump diffuser models with and without porous bed. Porous bed module is used to simulate the presence of metal foams in the primary zone and inside the inner fluid zone. The results are presented. The results show that the modified geometry dump diffuser model with porous bed can cool the exhaust gases to their condensation temperature. This model can be employed in automobiles to reduce air pollution.

“…In the liquid phase, a fluid such as mineral oil, water and glycol or a mixture of more than one fluid is generally used in nanofluids. Metal powders such as copper (Cu), aluminum (Al), nickel (Ni) and metal oxides such as aluminum oxide (Al 2 O 3 ) [6][7][8][9][10][11][12][13], copper oxide (CuO) [8][9][10][12][13][14][15], titanium oxide (TiO 2 ) [12,16], silicon oxide (SiO 2 ) [8,13] and carbon powders are used as nanoparticles. It has been stated in many studies in the literature that nanofluids show a better thermal performance than base fluid [17].…”

In this study, a computer model of the Zalman ZM-WB3 Gold heat exchanger which is one of the liquid-cooled computer processors in the market has been generated and the model has been confirmed by the previous researchers' models and experimental data. Then, the fin thickness and heights of the same heat exchanger and the type of liquid fluid in which the heat exchanger operates have been changed. The CFD analyzes of the new models were performed by using Ansys Fluent 17.1 program. Following that, nano heat removal (cooling) performances were investigated with models using rectangular fin fluid heat exchangers with different fin heights of 5 mm, 5.5 mm and 5.7 mm, and different fin thicknesses of 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm and 2 mm, and different fluids as water, copper oxide-water (CuO-H 2 O) nanofluids with volume ratios of 2.25% and 0.86%, and graphene oxide (GO-H 2 O) nanofluid with the volume ratio of 0.01%. It was concluded that the best CPU cooler performance could be achieved by using CuO -H 2 O as nanofluid with a volumetric ratio of 2.25% with a heat exchanger that has a 5.5 mm fin height and 2.0 mm fin thickness.
