Abstract
In the present study our intention is to dispatch the turbulent mixed convective flow and radiative flow in a vertical rectangular channel. The channel is constructed with two openings inlet and outlet. The turbulence is modelled by computational fluid dynamics (CFD) approach using lambremhorst turbulence model. Radiation is modelled with Discrete ordinates method (DOM). Finite difference method (FDM) is utilized to discretize the governing equations and an inhouse Fotron code is used to simulate the turbulent flow. The invariant study is carried out for the effect of flow opposite to buoyancy force and flow in same direction as buoyancy flow heat transfer characteristics. The heat transfer rate is remarkably altered by the flow opposite to buoyancy force and flow in same direction as buoyancy flow behavior observed inside the enclosure
Highlights
This Many Analytical and Numerical experiments have done for easy understanding of fluid and heat transfer process in the vertical channels
Tkachenko et al [1] performed analytical study in a vertical rectangular channel and found that common convective air entering the channel changing with the wall emissivities on the channel wall having Hot wall toward one side and cold wall on the opposite end discovered complex three dimensionless unsteady vortical structures
The unstable flow is customized by the computational fluid dynamics (CFD) approach using the Lambremhorst k-ε and turbulence model and is controlled using the finite difference method (FDM)
Summary
This Many Analytical and Numerical experiments have done for easy understanding of fluid and heat transfer process in the vertical channels. Tkachenko et al [1] performed analytical study in a vertical rectangular channel and found that common convective air entering the channel changing with the wall emissivities on the channel wall having Hot wall toward one side and cold wall on the opposite end discovered complex three dimensionless unsteady vortical structures. These structures began to shape ahead of schedule up stream and direct contact with the stream and warmth move in the channel. Andreozzi et al[3] performed analytical study on the unsteady common convection in air, channel-chimney
