Effects of inlet velocity profile and swirl on the cooling characteristics of a laminar jet

Discover Mechanical Engineering
The outcomes of numerical and experimental studies performed on a laminar circular swirling jet impinging on a flat surface is presented. In the numerical studies the computational domain is three-dimensional, which aids in predicting the complexity of ...

Experimental Investigation of Forced Convection in Plain or Partly Inserted Square Channel with Porous Media

Journal of Engineering
Several techniques are used to improve the channels' heat transfer coefficient and Nusselt number. One of the methods used for these improvements is porous media (PM).

INVESTIGATION OF CONVECTION HEAT TRANSFER FOR HIGH INTEGRAL FINNED TUBE HEAT EXCHANGER

Journal of Engineering and Sustainable Development, 2019
The numerical investigation has been performed in this work to evaluate the performance of a triangular finned tube heat exchanger. In numerical work, the effect of space (2.5, 3 and 3.5 mm) distance between every two finned shaped and the volumetric ...

Buoyancy Driven Heat Transfer in Cavities Subjected to Thermal Boundary Conditions at Bottom Wall

Journal of Applied Fluid Mechanics, 2012
Natural convection in cavities is studied numerically using a finite volume based computational procedure. The enclosure used for flow and heat transfer analysis has been bounded by adiabatic top wall, constant temperature cold vertical walls and a ...

Rayleigh-Bénard convection: bounds on the Nusselt number

, 2016
We examine the Rayleigh–Bénard convection as modelled by the Boussinesq equation. Our aim is at deriving bounds for the heat enhancement factor in the vertical direction, the Nusselt number, which reproduce physical scalings. In the first part of the dissertation, we examine the the simpler model when the acceleration of the fluid is neglected (Pr ...
