The combined impact of radiation and convection on the heat transfer of a wavy fin is scrutinized in the present analysis. The novelty of this research work is that it proposes a deterministic machine learning model known as an extreme learning machine to address the heat transfer problem of a wavy fin. The effect of radiation on convective heat transfer and the Rosseland approximation for the radiation heat exchange have been considered in the investigation. The nonlinear ordinary differential equation (ODE) is converted to its nondimensional form using the appropriate dimensionless variables. Runge-Kutta-Fehlberg's fourth-fifth order technique (RKF 45) is used to solve the nondimensional ODE numerically. The roles of convection-conduction, radiation-conduction, thermal conductivity, and radiation parameters have been discussed for satisfying a prescribed temperature distribution in rectangular and wavy fins with graphical visualization. A rise in convection-conduction and radiation-conduction variables decreased the thermal distribution of both the wavy fin and rectangular fin. Further, ANSYS simulation analyzes the variation of temperature and total heat flux in both rectangular and wavy fins. The study demonstrates the effectiveness of the model selected through the obtained results, which indicate the potential of the regression model for providing an accurate prediction.

“…They generated the results in form of variation in average and base heat transfer coefficient and average and base Nusselt number and they concluded a correlation to compute a Nusselt number as function of Rayleigh Number. Kaladgia et al [11] studied numerically the enhancement of heat transfer rate for rectangular fins with a circular perforation using ANSYS Fluent code. They analyzed the temperatures decreasing from a different of the circular shape perforations.…”

An experimental analysis of the heat performance and characteristics for natural convective from the different types of heat sinks to surroundings are reported. This research examines three various configurations of heat sinks namely, with solid fins, with single rectangular notched fins and with double rectangular notched fins. The impact of fins spacing, percentage of removal (notched) area and electrical power inputs with constant the aspect ratio for height to length of fin on heat convective performance and increased rate of heat transfer are analyzed and discussed. The current results appear the thermal performance for a double notched fin heat sink as average Nusselt number about 20% bigger than single notched fins heat sink and about 38% bigger than solid fins heat sink for same case of heat sink. Finally, the results have been compared than last experimental work, a good convergence are appeared.

The current work explores a trial forced convective heat move from rectangular blades on an upward surface at low Reynolds numbers. The heat removal for a proper number of punctured and non-punctured fins, fin dividing, and length was estimated in an upward air stream for fluctuating inlet air speed and some way or another low info heat power somewhere in the range of 20W and 70W. The characteristics are investigated for rectangular, circular, and Vshape perforated fin array against non-perforated one. The impact of different boundaries, like heat input with various liquid stream speed on average coefficient of heat transfer (h) improvement has been considered. The impact of the Nusselt numberand Reynolds number, were practically examined. The heat loss has been improved by increasing the heat transfer coefficient between the fin total surface and its encompassing, through increasing the area of heat to remove all out surface through fin perforations. The trial relations have been differentiated by correlating Nu and Re for nonpunctured plate heat sink, the reach 6*10 3  Re  19*10 3 , and Pr  0.7 with error ±7%, and punctured finned plate heat sink with the reach 6*10 3  Re  20*10 3 , and Pr  0.7 with a deviation factor R 2 =0.995.
