In this work, improved heat generation models are developed for straight and tapered shoulder geometries with different tool pin profiles in friction stir welding. The models are developed considering the welding process as a combination of the pure sliding and the pure sticking conditions. From the results, the amount of heat generation is directly proportional to the number of edges in the pi...

Numerous works have been carried out in the design and analysis of Heat Sink, however hardly any work reported with studies on dimples protrusions being added to heat sink geometries. This paper aims find worthiness for addition common plate fin geometries transfer enhancement. Analysis was forced convention environment 9 different velocities computationally 12 at constant flux boundary conditi...

Due to microscale effects, the segmented microchannels or micro pin fin heat sinks emerged as a high thermal management solution. In this context, present work analyzes influence of different heights square fins with an aligned array and investigates their on pressure drop transfer behavior. The HFE-7100 is used working fluid, surface temperature behavior are analyzed for mass fluxes inlet subc...

Nowadays, the heat transfer enhancement in electronic cabinets with heat-generating elements can be achieved using phase change materials and finned sink. The latter allows to improve energy transference surface augment cooling effects for sources. present research deals numerical analysis of material behavior an cabinet energy-generating element. For intensification removal, complex sink overa...

New design, experimental and numerical efforts, optimization and manufacturing process constitute the elements of investigation of this paper. The fundamental objective of the present study is to compute the thermal dissipation capability of a new design constructed for copper heatsinks and also deals with challenges in manufacturing of these components. A part of experimental efforts are condu...

the paper numerically presents laminar forced convection of a nanofluid flowing in a duct at microscale. results were compared with both analytical and experimental data and observed good concordance with previous studies available in the literature. influences of brinkman and reynolds number on thermal and hydrodynamic indexes have been investigated. for a given nanofluid, no change in efficie...
