A thorough grasp of the complex dynamics of pulsing flow is essential for improving heat transfer processes and creating effective systems, especially in situations where pulsations play a crucial role. Because pulsing flow has so many engineering applications, it has attracted a lot of attention when it comes to improving heat transmission. In this work, we examine several important factors influencing the properties of heat transmission, such as the Reynolds number (Re), length (L), diameter (D), frequency (f), and pulsation amplitude (A) of the pipe. All the results reported are for 3 − D configuration. Regarding turbulent kinetic energy (TKE), the mechanism is clarified for the various characteristics that are taken into consideration. The present work reports the results for a varied range of turbulent Re with different A, f, L and D. The impact of alterations of these parameters on its heat transmission properties is scrutinized. Also the TKE analysis is reported which provides insight into flow development and its effects on the heat transfer enhancement. It has been found that, in contrast to low frequencies, higher frequency pulsing velocity inputs boost the local Nusselt number (Nu) by penetrating the domain at a greater distance. Computational simulations using ANSYS Fluent are used to study a range of sinusoidal pulsating velocity inputs with different As and fs. The present study highlights how crucial it is to comprehend pulsating flow dynamics in order to optimize heat transfer procedures and create effective systems for use in engineering applications. It is advised to investigate a larger range of parameters in order to find the best mixes of fs and As for increased heat transfer efficiency.
