Direct numerical simulation of natural convection between an enclosure and multiple circular cylinders: An influence of horizontal arrangement of cylinders

Autor: Sudhanshu Pandey, Pradeep S. Jakkareddy, Young Min Seo, Man Yeong Ha

Publikováno v: Case Studies in Thermal Engineering, Vol 36, Iss , Pp 102205- (2022)

The work involves a three-dimensional numerical analysis of the buoyancy-driven heat transfer in an enclosure having four heated cylinders for Rayleigh number, Ra = 104-106, and Prandtl number, Pr = 0.7. An in-house direct numerical simulation code,

Estimation of heat transfer performance on mixed convection in an enclosure with an inner cylinder using an artificial neural network

Autor: Hyun Woo Cho, Young Min Seo, Yong Gap Park, Sudhanshu Pandey, Man Yeong Ha

Publikováno v: Case Studies in Thermal Engineering, Vol 28, Iss , Pp 101595- (2021)

The effect of variations in the aspect ratio (AR) of an inner cylinder on 3D mixed convection is examined by numerical means. Three Reynolds numbers are considered, Re = 100, 500, and 1000, with a fixed Grashof number of 105 and a Prandtl number of 0

Numerical study on the mixed convection around inclined-pin fins on a heated plate in vertical channels with various bypass ratios

Autor: Jun Seok Lee, Man Yeong Ha, June Kee Min

Publikováno v: Case Studies in Thermal Engineering, Vol 27, Iss , Pp 101310- (2021)

Natural and mixed convections around heat sinks with inclined-pin fins had been studied for various design parameters, showing that careful trade-off studies were necessary depending on operating conditions. Previous studies, however, assumed heat si

Publikováno v: Case Studies in Thermal Engineering, Vol 26, Iss , Pp 100997- (2021)

Given the highly complex thermo-hydrodynamic features in heat pipes (HPs) but the inevitable need for efficient thermal solutions, this study investigated the effects of various wick types on the time-dependent thermal behavior of HPs. The results re
