Natural convection heat transfer and fluid flow in a thermal chimney with multiple horizontally-aligned cylinders

Abstract:

To address the scarcity of natural convection research for the tube array with three or more columns of horizontallyaligned cylinders, this paper conducts RANS/URANS simulations for multiple cylinder columns in one or two rows, validated by particle-image velocimetry and heat transfer measurements. Parametric study with varying horizontal and vertical pitches is implemented by RANS with transition SST model. Key findings are then substantiated and examined by URANS. It is found that the horiz...
