Abstract
This article presents thermal performance analysis, flow visualization, and heat transfer characteristic in a round tube heat exchanger inserted with wavy V-rib. The novel design of the wavy V-rib ...
Highlights
Thermal performance improvement in heat exchangers has been done using vortex generators or turbulators
The results reveal that the optimal grid cell is found at grid around 180,000 cells when both time to investigate and accurate results are considered
The efficiency of the tube heat exchanger inserted with wavy V-rib is reported in terms of thermal enhancement factor or TEF, which is calculated from the ratio of the Nusselt number and friction factor at similar pumping power
Summary
Thermal performance improvement in heat exchangers has been done using vortex generators or turbulators. It can be concluded that the creation domain is reliable to predict flow and heat transfer mechanisms in the round tube heat exchanger inserted with wavy V-rib. The mechanisms on flow and heat transfer in the circular tube heat exchanger inserted with wavy V-rib are reported.
