Review of innovative approaches of thermo-mechanical refrigeration systems using low grade heat
(
Hindawi
, 2020 , Article)
Cooling and refrigeration systems consume around 17% of the world-wide electricity. Enhancing the performance of these systems, using renewable energy resources and waste heat recovered from industrial processes, will lead ...
Heat transfer measurements of Polyalpha-Olefin- boron nitride nanofluids for thermal management and lubrication applications
(
Elsevier
, 2020 , Article)
In this paper, the first study is reported combining Polyalpha-Olefin (PAO) oil with hexagonal Boron Nitride (hBN) to produce new class of nanofluids for heat transfer and lubrication applications. The heat transfer ...
Turbulence Modeling Using Z-F Model and RSM for Flow Analysis in Z-SHAPE Ducts
(
Wiley
, 2020 , Article)
Turbulent flow in Z-shape duct configuration is investigated using Reynolds stress model (RSM) and ζ-f model and compared to experimental results. Both RSM and ζ-f models are based on steady-state RANS solutions. The focus ...
Isobaric Expansion Engines Powered by Low-Grade Heat-Working Fluid Performance and Selection Database for Power and Thermomechanical Refrigeration
(
Wiley-VCH Verlag
, 2020 , Article)
A database is developed for the most suitable working fluids for Worthington-type and Bush-type isobaric engines based on their performances for a wide range of heat source temperature, from 40 to 300 °C, and operating ...
Large-eddy simulation of the flow in Z-Shape duct
(
Cogent OA
, 2020 , Article)
A numerical study is conducted of the transient flow in a z-shape three-dimensional duct using large-eddy simulation (LES) with dynamic eddy viscosity subgrid-scale (SGS) model with a fully structured grid system. The ...
