Numerical Investigation for Single-Phase and Two-Phase Flow in Duct Banks with Multi Types of Vortex Generators

This paper examines the numerical work of thermal convection over tube banks with winglets through heat exchanger in two parts under turbulent conditions. The first section investigates influence two-phase (water and air) flow on performance kinds vortex generators (Delta Rectangular) across oval banks. second studied four types (Delta, Rectangular, Zikzak, Sinusoidal wavy), circular tubes, forward downward configurations, various angles attack (15°
