Comparative Investigation of Novel Thermo-Hydraulic Flow Characteristics and Augmentation of Heat Efficiency in 3D Pipes Based on Parametrical Corrugated Shape Configurations

Abstract

This study investigates the effects of various corrugation shapes on heat performance and pressure drop characteristics in 3D pipe surfaces. Evaluating corrugation pipes' thermo-hydrodynamic performance with respect to different corrugation configurations and Re is the main goal. The smooth flow is broken up in the double-dimpled corrugated shape, causing tiny swirl zones to form and creating turbulence that increases heat exchanger performance and keeps particles from falling out of suspension. A heat exchanger is made possible by the corrugation's distinctive design, which improves heat transfer. Corrugated heat exchangers have the ability to alter the dimensions of smooth ones based on the application, whenever companies want a compact size for operation. Numerical simulations at Re ranging from 4000 to 12,000 are carried out under the assumption of a steady and consistent heat flux of 10,000 W/m². Utilizing various models, the computational fluid dynamics solver is utilized to examine the effective characteristics of corrugation. The outcomes of temperature distributions, pressure drop, heat transfer coefficient, Nu, and f factors under various circumstances are discussed. For the conventional pipe, it was shown that different corrugation forms had a 22%–30% higher heat transfer coefficient. Because of the intricate corrugations, which enhance heat transfer and pressure drop, a greater Nu is achieved. Because corrugated geometries have a performance assessment criterion PEF greater than unity, they can outperform smooth pipes.
