Abstract
A significant laminar heat transfer enhancement in a
2:1 rectangular duct occurs when a dilute aqueous polyacrylamide solution is used. There is strong evidence that this enhancement might be due to the effect of temperature on the viscosity of the polyacrylamide solution particularly at the low shear rate. However, there is no experimental data that reports this low shear viscosity over a range of temperature. The objective of the study is to report viscosity data which depend on both shear rate and temperature and to develop a method to correlate the viscosity data using a mathematical equation. A new temperature-dependent viscosity equation based on the Carreau model is introduced; this model takes into account the effects of shear-thinning non-Newtonian characteristics and temperature on the viscosity of the polyacrylamide solution.
