Fins are the extended surfaces designed to Increase heat transfer rate for a fixed surface temperature, or lower surface temperature for a fixed heat transfer rate. Heat transfer by convection between a surface and the fluid surrounding can be increased by attaching to the surface called fins.

We plot temperature of the pin fin as a function of the distance of points of thermocouple along the length of the pin fin from the heating end. Thus, through this experiment we have successfully determined the efficiency of the fin used in this set up.

Aug 28, 2024 · This work provides a detailed introduction to the application of pin-fins in enhancing heat transfer, including the conventional shape, improved and irregular shape, layout of pin-fin and optimization techniques of pin-fin shapes and layout.

In an air-cooled I.C engine, extended surfaces called fins are provided at the periphery of engine cylinder to increase heat transfer rate. That is why the analysis of fin is important to increase the heat transfer rate.

Temperature fluctuations in different areas of the pin fins are evaluated using FEM, and the plate fin results are compared with the experimentally determined pin fin results in Ansys. The principle implemented in this design is to increase the heat dissipation rate by using wind flow.

Apr 1, 2023 · A parametric study on an air-cooled engine was done by Memon et al. [31] to get the optimum fin length, fin spacing, fin thickness, and fin profile. Considering a given heat flux, using CFD and numerical methods, various fin parameters, as mentioned above, have …

parametric evaluation with different configuration of pin fin including impingent flow, the final observation is the optimum ratio of distance between fin and spacing ratio develops

In this section, we will analyze certain basic forms of fins, with respect to heat rate, temperature distribution and effectiveness. The experiment is conduct to investigate the effect of the pressure loss and heat transfer characteristics in pin-fin channel, where dimples are located on the pin-fins.

Feb 1, 2016 · In this study, the performance of a surface air–oil heat exchanger for an aero gas-turbine engine having plate- and pin–fin shaped geometries was investigated numerically. Basic heat-transfer and pressure-drop characteristics were examined using a simplified channel model.

Sep 24, 2024 · For safe turbine blade operation, internal cooling is essential. Ribs, pin-fins, and impinging jets are just examples of the several different types of structures that are typically included in internal cooling systems. The present study investigates the effect of rib placed in between the pin fins in a wedge channel.
