Heat Effect and Temperature Rise for Circular Tube Laminar Flow
Viscous heat effect for laminar flow in circular tube has been investigated by various authors1.–4., and solved analytically under the condition that the tube walls are kept at the constant temperature, or that the tube walls are thermally insulated. Therefore, those results can be applied to the system where the thermal conductivity of the tube is relatively large or small enough. But when the thermal conductivity of the tube is comparable with that of fluid and the thickness of the tube is comparable with the tube bore, their results are not effective. So authors investigate the viscous heat effect and the temperature rise in circular tube laminar flow when the heat drain passing across the tube walls is not negligible.
