Hydraulic Network Modeling to Analyze Stream Flow Effectiveness on Heat Transfer Performance of Shell and Tube Heat Exchangers
In this article, stream flow effectivness is based on hydraulic network studied in the shell-side of a shell and tube heat exchange as a case study. For an appropriate heat exchangers rating design to meet a specified duty, it's better to consider each stream flow separately. Using the hydraulic network principals, a set of the correlations for calculating different stream flow rates in the cro...
متن کاملApplication of ZnO/TiO2 Nanocomposite for the Improvement of Heat Transfer Coefficient in Tube Heat Exchangers
The potential of nanofluids for the improvement of heat transfer coefficient in various heat exchangeequipment has been considered and studied as a major application during recent decades. In this research,heat transfer coefficient of ZnO, TiO2 and ZnO/TiO2 nanofluids in a shell and tube heat exchanger has beenstudied experimentally. ZnO nanoparticle was synthesized through pre...
متن کاملExtended Correlations for Staggered Round Tube Plain Fin Heat Exchangers
This paper develops a semi-empirical expression for heat transfer in round tube plain fin heat exchangers that have relatively large fin pitch. Empirical heat transfer correlations currently available in the public domain are necessarily limited in their range of applicability, and their functional forms are generally not designed to converge to well-known physical results, for example when par...
متن کاملBoundary layer Viscous Flow of Nanofluids and Heat Transfer Over a Nonlinearly Isothermal Stretching Sheet in the Presence of Heat Generation/Absorption and Slip Boundary Conditions
The steady two-dimensional flow of a viscous nanofluid of magnetohydrodynamic (MHD) flow and heattransfer characteristics for the boundary layer flow over a nonlinear stretching sheet is considered. Theflow is caused by a nonlinear stretching sheet with effects of velocity, temperature and concentrationslips. Problem formulation is developed in the pre...
متن کاملThree-Dimensional Boundary Layer Flow and Heat Transfer of a Dusty Fluid Towards a Stretching Sheet with Convective Boundary Conditions
The steady three-dimensional boundary layer flow and heat transfer of a dusty fluid towards a stretching sheet with convective boundary conditions is investigated by using similarity solution approach. The free stream along z-direction impinges on the stretching sheet to produce a flow with different velocity components. The governing equations are reduced into ordinary differential equations b...
