A Numerical Investigation of Compact Spiral Fin Heat Exchanger for Circular Tubes with Hydrophilic Coating

This study presents the airside performance of fin and tube heat exchangers for perforated serrated spiral fin with Hydrophilic coating, this research focus on heat and fluid flow analysis by various fin pitches. A steady –state three-dimensional numerical model is going to be used to study the heat transfer and pressure drop characteristics of spiral fin on the tube surfaces with Reynolds number in the range of 1000-1600.A numerical study is going to be perform on compact fin and tube heat exchanger having circular tube with serrated spiral fins. The air side performance for heat exchanger with combination of with hydrophilic coating and without hydrophilic coating on a fin and different fin pitches and also different twist angle of fins. The increase in the heat transfer performance will be analyzed for various fin pitches of 2mm to 3mm with combined coating. The effect of number of tube rows, fin pitch on airside performance will be analyzed.
