IILaminar flow heat transfer and pressure drop characteristics in a circular tube fitted with regularly spaced twisted-tape elements connected by thin circular rods were investigated experimentally. These characteristics are governed by Reynolds number, Prandtl number, twist ratio, space ratio, and
The phenomenon of combined forced and free convection heat transfer in laminar boundary layer flows, in which the momentum equation is coupled with the energy equation on account of the presence of the gravitational term, is analyzed theoretically. It is shown that for large values of the Prandtl nu
