... affected by the distance between the two walls. In the same way, the effect of wall roughness on the thermal conductivity is investigated, which shows that roughness is effective only for low distances between the walls. Also, the thermal conductivity of argon under Poiseuille flow in a nanochannel is...

... Poiseuille flow at Reynolds numbers of 3.3 and 8.3 through a 1 mm 2 heated minichannel. Water temperatures in the bulk flow (i.e., away from the walls) were measured using DFT with an average uncertainty of 0.2 °C at a spatial resolution of 30 μ m. Temperatures within the first 0.3 μ m next to the wall were...

... separated by a finite distance. The method is successfully applied to study the constant viscosity models, namely plane Couette flow, plane Poiseuille flow, and plane Couette–Poiseuille flow for velocity fields and the temperature distributions. Numerical solutions of the systems are also obtained using a...

... consists of a glass tube coated with a transparent indium tin oxide heater film. For single-phase liquid flow (including superheated liquid) it was found that the measured Nusselt numbers and friction factors are in good agreement with the theoretical values expected from Poiseuille flow. Subsequently, the...
