TLDR
In this article, the effect of time-dependent pressure pulsations on heat transfer in a pipe flow with constant temperature boundaries is analyzed numerically when the viscosity of the pulsating fluid is an inverse linear function of the temperature.Abstract:
The effect of time-dependent pressure pulsations on heat transfer in a pipe flow with constant temperature boundaries is analysed numerically when the viscosity of the pulsating fluid is an inverse linear function of the temperature. The coupled differential equations are solved using Crank-Nicholson semi-implicit finite difference formulation with some modifications.read more
