چکیده

influence of a vent hood at the exit of exhaust flue gas and flue baffles in the firetube on the temperature and flow fields of a gas tank water heater, as well as thestructure and amount of heat transferred to the water tank has been studiednumerically using two-dimensional steady state finite element simulation.observations show that without a vent hood, there is a downward gas flow in theflue and a strong vortex in the lower burner chamber. using a vent hood preventsthe gas back flow into the flue, and placing the flue baffles increases the heatdelivered to the water

Fluid flow and heat transfer characteristics in a curved rectangular duct using Al2O3-water nanofluid

In the present research, the laminar forced convective heat transfer and fluid flow characteristics for Al2O3-water nanofluid flowing in different bend (i.e., 180o and 90o) pipes have been investigated numerically in a three-dimensional computational domain using the finite volume technique. The effects of different pertinent parameters, such as the Reynolds number of the duct, volume fraction ...

Fluid Flow and Heat Transfer of Nanofluids over a Flat Plate with Conjugate Heat Transfer

The falling and settling of solid particles in gases and liquids is a natural phenomenon happens in many industrial processes. This phenomenon has altered pure forced convection to a combination of heat conduction and heat convection in a flow over a plate. In this paper, the coupling of conduction (inside the plate) and forced convection of a non-homogeneous nanofluid flow (over a flat plate) ...
