Forced Convection Heat Transfer of Non-Newtonian Fluids Through Circular Ducts
The Galerkin finite element method is used to solve the three dimensional continuity, momentum and energy equations for laminar Newtonian and power-law model non-Newtonian flow through horizontal circular tube. The governing equations are non-dimensionalized with respect to specific variables and converted into algebraic equations using appropriate elements. To accelerate convergence a combinat...
متن کاملAverage Heat Transfer Coefficient in Rectangular Ducts with Baffle Blockages
An experimental investigation was conducted to study the average and the fully-developed heat (mass) transfer coefficients in a rectangular smooth duct and a duct with repeated-baffle blockages. The focus of attention in this work is the conventional correlation Nu / Nufd 1 + C / ( X / D ) for the average heat transfer coefficient. It was shown that for relatively short ducts, the coefficient C...

متن کاملModeling heat and mass transfer in laminar forced flow between parallel plates channel imposed to suction or injection
A numerical model is developed to simulate the transport phenomena in the flow channel between parallel plates with porous and non-porous (or impermeable) walls. The continuity and momentum equations were solved first, assuming the wall Reynolds number in the range of with the suction or injection of air at a speed equal to the uniform inlet velocity. The results show that at constant inlet and...
متن کاملLaminar Forced Convection Modeling of Isothermal Rectangular Plates
A composite model for area-average Nusselt number for forced, laminar ow parallel to a nite, isothermal rectangular plate for a wide range of Reynolds numbers is proposed. The correlation equation is based on the superposition of the dimensionless shape factor and a modi ed laminar ow boundary-layer asymptote with an empirically determined interpolation parameter. The Nusselt and Reynold...
