RISInvestigation of Shroud Geometry to Passively Improve Heat Transfer in a Solar Thermal Storage Tank
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A shroud and baffle configuration is used to passively increase heat transfer in a thermal store. The shroud and baffle are used to create a vena contracta near the surface of the heat exchanger, which will speed up the ...
On the Validation of Turbulence Models for Wheel and Wheelhouse Aerodynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Vehicle aerodynamics plays an important role in reducing fuel consumption. The underbody contributes to around 50% of the overall drag of a vehicle. As part of the underbody, the wheels and wheelhouses contribute to ...
Special Issue: Innovations and Advancements in Heat & Mass Transfer: Celebrating the Legacy of Professor Ephraim M. Sparrow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The passing of Professor Ephraim M. Sparrow on Aug. 1, 2019, left a large void in the worldwide heat and mass transfer community. To many in the field, he was an intellectual giant, who famously was the “most cited” ...
Effect of the Heat Transfer Coefficient Reference Temperatures on Validating Numerical Models of Supercritical CO2
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Validating turbulence models for cooling supercritical carbon dioxide (sCO2) in a horizontal pipe is challenging due to the lack of experimental data with spatially resolved local temperature measurements. Although many ...
Optimizing Jets for Active Control of Wake Refinement for Ground Vehicles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present study investigates active drag reduction of an Ahmed body with a rear slant angle of 25 deg. The drag is reduced by implementing slot jets on the rear slant and rear surface of the Ahmed body. Transient ...
Experimental and Numerical Investigation of Lauric Acid Melting at Suboptimal Inclines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Accurate modeling of melting and solidification processes is important to many engineering applications. The research presented in this article is part of an ongoing effort to document the melting behavior of lauric acid ...
Special Section on Flow Physics of Supercritical Fluids in Engineering
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Supercritical-fluid applications have recently received extensive attention. Applications of supercritical flows include thermal power generation, cooling of scramjet engines, highly efficient compact power systems, ...
Effect of Porosity Gradient on the Solidification of Paraffin in a Thermal Energy Storage Tank Filled With Metal Foam
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Thermal energy storage (TES) systems are a promising solution for reutilizing industrial waste heat (IWH) for distributed thermal users. These systems have tremendous potential to increase energy efficiency and decrease ...
Special Issue: Richard J. Goldstein Memorial Issue—Transformative and Innovative Advancements in Heat and Mass TransferA Lifetime of Path-Breaking Scholarship That Spans Gas-Turbine Cooling to Transport Processes and Critical Diagnostic Tools for Convecti
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Professor Richard J. Goldstein (March 27, 1928–March 6, 2023) was perhaps one of the “tallest” colleagues in our field with a career spanning over seven decades, during which he contributed extensively to a gamut of heat ...
Laminar Natural Convection From Isothermal Vertical Cylinders: Revisting a Classical Subject
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Although an extensively studied classical subject, laminar natural convection heat transfer from the vertical surface of a cylinder has generated some recent interest in the literature. In this investigation, numerical ...
