Elliptical Finned Tube Heat Exchanger are most used for forced air heating and cooling system.
Usually, liquid passing through the tube and water-vapor flows over fin and tube.
Tubes have been taken as a staggered arrangement in this work.
Oval tubes have been using in recent years.
For having a better aerodynamic shape of an elliptical tube, there has some advantage in compactness, high heat transfer coefficient, and lower pressure drop.
