Abstract	Energy loss characteristics of heat transfer and fluid flow due to forced convection of steady laminar flow of incompressible fluid in a helical coil is analysed. This paper analyses energy loss and pumping power in the fully developed laminar convection in a helical coil with constant wall heat flux. The important design parameters, including Reynolds number (Re), coil to tube radius (δ) and dimensional coil pitch (λ) are varied to investigate their influences on the energy loss and pumping power values. Amount of heat transfer is the primary concern in a heat exchanger design. The amount of energy loss during the heat exchange process has been investigated by introducing a new dimensionless number This dimensionless number has been defined as the energy loss to total heat transfer rate ratio. The energy loss dimensionless number behavior have been compared with entropy generation dimensionless number behavior for this problem.
