Numerical Study on Thermal and Flow Characteristics of Air in a Square Duct using Delta Wing Vortex Generators

Abstract

The impact of delta wing vortex generators in a square duct on the thermal and flow characteristics execution has been numerically explored in this study. The vortex generator allows the air flow to distribute more and occupy larger contact area in the channel. In the present project thermal and fluid flow analysis of air in a rectangular channel with delta wings are carried out. Analysis is carried out by using a commercially available CFD tool and analysis is carried out for the combination of Aspect Ratio of 1.6, 2.4 and 4.8 for varied pitch of 150 mm, 240mm, 180mm and 100mm. Primary objective of the analysis is to analyze the effect of varied aspect ratios of delta wings with varied pitch on the heat transfer rate and to estimate the pressure ratios in the rectangular channel. From the present analysis it is concluded that for model with higher aspect ratio and longer pitch results in lower pressure drop and better heat loss for the given inlet flow conditions. Also it is found that aspect ratio of a delta wings is not making impact on the pressure drops in the channel.
