Cuo nanofluid has volume concentration (∅) of 3% in laminar to turbulent flow condition at constant heat flux condition. Numerical Results show enchantment in Nu, f and η with HSTT inserted tube whereas also shows increment with nanofluid compares to PT. Maximum thermal performance factor (η) achieved with the nanofluid flow in a pipe with HSTT compare to water. © 2019 Elsevier Ltd. All rights reserved.

Introduction Heat transfer is an essential aspect of increasing the efficiency of the heat exchanger which is the need for reducing the size of many applications where heat exchanger used like refrigerator, radiator, power plant and many more. The swirl effect of fluid flow occurs by the insertion of twist tape insert that is why disturbance occurs in the tube [1]. Helical vortices increase the contact of the fluid with the heated surface of the plain tube due to decrement in the thermal boundary layer which gives increment in heat transfer [2] [3]. Inserts induce vortex mixing and Tube blockage in flow that is why achievement of an increase in Nu and f [4]. * Corresponding author. E-mail address: ranjan.shashank88@gmail.com
