RISRole of Heating Location on the Performance of a Natural Convection Driven Melting Process Inside a Square-Shaped Thermal Energy Storage System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this work, numerical experiments were performed to compare the heat transfer and thermodynamic performance of melting process inside the square-shaped thermal energy storage system with three different heating configurations: ...
Direct Numerical Simulation of a Low Prandtl Number Rayleigh–Bénard Convection in a Square Box
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Direct numerical simulations for low Prandtl number fluid (Pr = 0.0216) are used to study the steady-state Rayleigh–Bénard convection (RB) in a two-dimensional unit aspect ratio box. The steady-state RB convection is ...
Three-Dimensional Numerical Investigation of Thermodynamic Performance Due to Conjugate Natural Convection From Horizontal Cylinder With Annular Fins
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Entropy generation due to natural convection has been computed for a wide range of Rayleigh numbers based on fin spacing, RaS in the entire laminar range 5≤RaS≤108, and diameter ratio 2 ≤ D/d ≤ 5 for an isothermal horizontal ...
Entropy Generation in Laminar and Turbulent Natural Convection Heat Transfer From Vertical Cylinder With Annular Fins
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Entropy generation due to natural convection has been calculated for a wide range of Rayleigh number (Ra) in both laminar (104 ≤ Ra ≤ 108) and turbulent (1010 ≤ Ra ≤ 1012) flow regimes, for diameter ratio of 2 ≤ D/d ≤ 5, ...
