TL;DR: In this paper, a long heating test section (627 diameters) with a uniform heat flux boundary condition is constructed in order to study the effects of the phase change phenomenon produced by a phase-change material (PCM)-water slurry on the convective heat transfer coefficient in a turbulent flow.

TL;DR: In this paper, the effect of the temperature-dependent and shear-thinning viscosity of a non-Newtonian fluid on the behavior of laminar heat transfer and friction coefficients in a 2:1 rectangular duct was investigated.

TL;DR: The analogy between the DNA molecule and a thin cylindrical body in the polyacrylamide solution suggests that when one perfects the separation device, very large DNA molecules can be separated using a viscoelastic solution.

TL;DR: In this article, the authors measured the terminal velocity of a falling ball or needle in the falling ball viscometer and determined the apparent viscosity and the characteristic time of aqueous polyacrylamide Separan AP-273 solutions by using two laser beams and a digital timer system.
