An Experimental Investigations of Nusselt Number for Low Reynolds Number in an Agitated Helical Coil
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2014, Vol 4, Issue 12
Abstract
In this paper, we present results of measured heat transfer coefficients for each sodium carboxymethyl cellulose concentration at two different lengths of coil L=2.82m, L=2.362m and with two different heat inputs 1.0kW and 1.5kW . Test solutions of sodium carboxymethyl cellulose concentrations of 0.05%, 0.1%, 0.15% and 0.2% were used in our experimental runs. A four flat blade paddle impeller was used to verify the mixed fluid, under steady heating of Newtonian and nonNewtonian fluids in an flat bottom agitated vessel. A Kanthal Heating Element Equipment have been design and fabricated to optimize the heating of the fluids in an agitated vessel. The rehogical properties like flow behavior index, consistency index and viscosity data were carried experimentally using Rotating Cylinder Method for all the test solutions. A correlations have been presented for Newtonian and non Newtonian fluids in laminar flow conditions.
