Numerical Simulation and Parametric Study of Forced Convective Condensation in Vertical Channel
Authors: not saved
Abstract:
Forced convective condensation in vertical channel is investigated numerically. The condensation boundary layers that occur due to temperature difference between the walls and saturation temperature of steam is simulated by the volume of fluid (VOF) method. The effect of variations in the hydraulic diameter, steam velocity, Re number and temperature difference between the wall and saturation temperature of inlet steam on heat transfer coefficients are investigated. Simulation results showed that the condensation length and heat transfer coefficient increase by the increase in the amount of inlet velocity and Reynolds number of inlet steam. Also, it was seen a reduction in temperature difference between the wall and saturated steam.

Numerical study of turbulent forced convection jet flow of nanofluid in a converging sinusoidal channel
Research in convective heat transfer using suspensions of nanometer-sized solid particles in base liquids started only over the past decade. Recent investigations on nanofluid, as such suspensions are often called, indicate that the suspended nanoparticles remarkably change the transport properties and heat transfer characteristics of the suspension. Bending walls can also improve heat transfer...

Natural convection between vertical parallel plates occurs frequently in applications such as solar collectors and cooling of electronic instruments. The problem is a two dimensional developing buoyant flow. In this work, the two dimensional conservation equations are solved numerically for constant wall temperature and constant wall heat flux. The results for the local Nusselt number at the du...

This study presents direct numerical simulations of natural convection for air (Pr = 0.709) in a vertical channel driven by differentially heated walls at Rayleigh numbers (Ra) up to 2.0 × 107. The present data is validated with that from Versteegh and Nieuwstadt [9] for Ra = 5.0 × 106. Using the present data for higher Ra, we appraise and compare the various proposed scaling laws for the mean ...

A steady MHD free and forced convective viscous incompressible electrically conducting flow in a rotating channel under constant pressure gradient has been studied. An exact solution of the governing equations has been obtained in closed form. The numerical results for the velocity components, the induced magnetic field components and the temperature distribution are being presented graphically...
