Experimental Investigation On Characteristics of Non-Newtonian Fluids

  Sudarshan B.,  Victor Seram,  Narayan U Rathod

The non-Newtonion fluid behavior in a pipe flow with respect to the Newtonion fluid has been characterized using the experimental technique through velocity profile, wall shear stress and shear rate parameters. In a specially designed set up, the stagnation and static pitot tubes are used to find the pressure head of the Newtonian and non-Newtonian fluid at a particular point inside the pipe. From the obtained pressure head, the velocity profile is plotted for each fluid. The Aqueous Sodium Bentonite solution (Al2O3.4(SiO2).H2O) and Sodium Carboxymethyl Cellulose solution ([C6H7O2(OH)2OCH2COONa]n) are used as the experimental non-Newtonian fluids and the water is used as a reference fluid, a Newtonian fluid, to do the comparative study of characteristics Similarly, experiments have been done by placing the sphere obstacle in the flow domain. The velocity profiles in the flow area, after the obstacle, are been plotted. The same Newtonian, water, and non-Newtonian fluids, Aqueous sodium bentonite solution and sodium carboxymethyl cellulose solution, are been used. Correspondingly the wall shear stress and shear rate of the fluids are calculated and plotted against the length of the pipe. The comparative study has been done.
