The effect of the twisted tape with different twisted ratios are numerically investigated on the heat transfer rate and friction factor to determine the optimum twisted ratio that give the highest heat transfer rate and the best thermal performance factor.The twisted tape with rod, helical twisted tape with rod, alternated clockwise and counterclockwise twisted tape, and vortex generators inserts are numerically investigated. Comparisons between these inserts and the plain tube are performed based on the heat transfer rate, friction factor, and the performance evaluation criteria
CFD Friction factor Nusselt number
