We develop and computationally analyze a mathematical model for natural convection to non-Newtonian fluid in long thin channel. The channel is bounded by antisymmetric heated cooled walls encloses pseudoplastic fluid. flow heat transfer characteristics are investigated subject the prevailing buoyancy forces resulting from combined gravitational effects. An efficient accurate semi-implicit finit...

The appropriate estimation of frictional losses in a pipeline system is essential. So far, little attention has been paid to determining the friction factors with non-Newtonian fluids, especially rough pipes. This study aims at calculating factor using validated three-dimensional Computational Fluid Dynamics models Ansys CFX. Steady-state computations are performed three different incompressibl...

An experimental study was carried out to obtain the mean convective heat transfer coefficient of aqueous carboximethyl cellulose (CMC) solutions in double-pipe heat <span style="font-size: 10pt; color:...

This communication presents a progress report on an ongoing project aiming at the computation of complex fluid flows with a realistic constitutive law, which would takes into account the pseudoplastic, viscoelastic and thixotropic behaviour of the materials. The flow solver is based on the LS-STAG method, which is an immersed boundary (IB) method that allows the computation of flows in complex ...
