Abstract: Professor Roop L. Mahajan, ASME Fellow and Lewis Hester Chair Professor of Engineering at Virginia Tech celebrated his 80th birthday on Mar. 5, 2024. On this wonderful occasion and to honor his remarkable career, his former ...

Abstract: Among the methods used to enhance heat transfer, the insertion of porous media is prominent. Metallic foam is one of the most commonly used porous media in recent years; however, it presents a disadvantage due to its high ...

Abstract: Heat transfer in porous materials is of great importance for various natural, biological, and industrial processes. For the large difference between the microscopic and macroscopic dimensions, the volume averaging method ...

Abstract: Diffusion-reaction phenomena occur commonly in heat and mass transfer problems. Determining the decay characteristics of such problems by solving the underlying energy/mass conservation equation is often mathematically ...

Abstract: Heat transfer and pressure loss characteristics of a novel Vortex rib in a cooling channel have been studied both experimentally and numerically under the Reynolds numbers from 10,000 to 80,000 and rotation numbers from 0 ...

Abstract: The current study is concerned with the numerical simulation of the phase change process in a two-dimensional (2D) dual-phase-lag (DPL) bioheat model applied to nanocryosurgery. A Gaussian radial basis function (RBF) ...

Abstract: This paper investigates the forced convection of alumina-water nanofluids within helical tubes, maintaining a constant wall temperature and assuming thermal equilibrium between the nanoparticles and the base fluid. The ...

Abstract: This article reflects on the author's research career, which has focused on heat and energy. It details the challenges faced by the author and his research group, highlights their successes and failures, and explores some ...

Abstract: This paper outlines an experimental investigation into fundamental nucleate boiling phenomena involving finned surfaces within a narrow channel. The study delves into the effects of both channel width (2.0 mm and 0.5 mm) ...

Abstract: This study proposes a novel multi-scale numerical method for thermal-mechanical analysis of mini-channel heat exchangers (MCHEs) under internal fluid pressure and temperature loads. The method comprises a macro-scale model ...
