“…Later, Mangrulkar et al (2017) also reported the increased heat transfer and reduced pressure drop due to SP in finned tube heat exchanger. Razavi et al (2015) and Sajedi et al (2016) placed the SP kind arrangement in the downstream of pin fin of a heat sink, the investigation shows that the SP reduces the pressure drop and thermal resistance. Sajedi et al (2016) reported the splitter usage in a circular pin fin heat sink is more efficient than square pin fin heat sink.…”

The location and orientation effect of control plates (CP) in and around the flow separation region of a circular cylinder has been numerically investigated in the laminar flow regime at Reynolds number 100. The vortex shedding and convective heat transfer characteristics have been analysed for both upstream and downstream locations of the control plates using Ansys Fluent 18.0. The drag and lift coefficient (C D , C L ), the dimensionless vortex shedding frequency (Sr) and dimensionless convective heat transfer coefficient (Nu) are reported for various CP orientation and locations. The CP positioned along the main flow direction and located near the cylinder induce more shear on the cylinder surface, stabilities the wake vortices. In addition to shear generation, the CP orientation interacts effectively with the cylinder wake. The vortex shedding suppression with reduced drag on the cylinder is identified at many locations of CP. Convective heat transfer from the cylinder is suppressed at most of the locations of CP, at very few locations the cylinder heat transfer enhanced.

Improving the thermal design of geometric Heat Sinks (HSs) reduces their size and weight and improves heat dissipation, hence enhancing the speed of electronic devices. In this numerical study, a novel thermal design of HSs is proposed by inserting various forms in order to obtain the optimum thermal design for this type of HSs. This study has two primary objectives: determining the influence of varying types of HSs while maintaining the volume of fins, and introducing new geometries such as circular fin and circular cut fin. The tests were conducted with a heat flux of 11.1 kW/m2 and a Reynolds number (Re) ranging from 2418.56 to 819.19. For forced convection, three-dimensional numerical simulations utilising the Navier–Stokes equations laminar model and energy equation are acquired using the commercially available COMSOL Multi-physics version 5.6a CFD software. The results indicate that. A comparison analysis of HSs with different geometries revealed that the circular-cut shape exhibited the highest thermal efficiency, as measured by the Nusselt number about 153 as well as the heat transfer coefficient and the minimum thermal resistance.
