Abstract— Heat transfer enhancement techniques are of different methods which used to increase rate of heat transfer without affecting much overall performance of the system. As these techniques are used in heat exchangers. The heat transfer enhancement can be done by using passive technique just by changing the flow geometry, boundary conditions, or by enhancing the thermal conductivity of the fluid. Much research has been takes place to increase the heat transfer rate by increasing the thermal conductivity of fluid with twisted tape type of insert. Increase in thermal conductivity can be achieved by use of nanopowder with base fluid. The present paper mainly focuses on the twisted tape heat transfer enhancement with nanofluid.
