PROJECT ON CFD ANALYSIS ON ROTATING ANNULUS

To study effect of fluid flow and heat transfer through rotating annulus in which fluid is flowing

in axial direction. Below, figure show the physical and computational models wherein inner

cylinder is rotating with an angular velocity ω rad/sec and outer cylinder is kept stationary.

Physical Model Computational model

Axial Velocity Distribution at 0.8L from inlet of annulus for Axial flow Reynolds Number

3000 and 11000 respectively for water

As rotational Reynolds number increases the magnitude of axial velocity will decreases

only at low axial Reynolds number but at high axial Reynolds numbers the effect of

rotation will diminish.

Swirl Velocity Distribution at 0.8L from inlet of annulus for Axial flow Reynolds Number

3000 and 11000 respectively for water

The axial Reynolds number has no significant effect on swirl velocity. As the rotational

Reynolds number increases the hydrodynamic boundary layer become thinner and is

nearer to inner rotating wall.

Temperature Distribution at 0.8L from inlet of annulus for Axial flow Reynolds Number

3000 and 11000 respectively for water

As rotational Reynolds number increases, fluid temperature increases due to decrease in

wall temperature which is the result of high rate of transfer of thermal energy from the

inner wall to fluid.

Nusselt Number variation with Rotational Reynolds Number

As rotational Reynolds number increases, Nusselt number also increases for low axial

Reynolds number and at high axial Reynolds number the effect diminishes.

M INI PROJECTS

1. Heat transfer from Custard Apple during its conversion from wet/raw condition to dry condition.

What was the problem? We kept it in the material made up of Aluminium due to which it was not

getting dried then I observed that the Aluminium has higher thermal conductivity than steel due to

which more and more heat transfer was taking place from Custard Apple to environment.

Q = K A dT/dx

Where Q = Heat transfer rate; K = Thermal Conductivity of material; A = Area normal to

direction of heat transfer; dT/dx = Temperature gradient.

From where the Heat was developing inside the material even though I was supplying the heat?

The water vapour present in the atmosphere try to convert into liquid by the method of

condensation. During its condensation process the water vapour gives its latent heat to the

Custard Apple, due which it becomes hot and gets dried.

So we have to keep the Custard Apple in vessel which has very low thermal conductivity like

wood.

2. During cooking of carrot’s sweat, the carrot was not getting soften quickly when we boiled by

adding water. Why? Because in my home my sister was cooking it by uncovering vessel’s head.

What happens when it is covered? The water which is converted into vapour gets accumulated

between the free liquid surface and cover head of vessel and indirectly the heat loss from the

vessel to the environment is reduced. Hence the carrot inside the vessel gets more heat (both from

bottom of vessel and from the water vapour).

Hence the time required for making the carrot’s sweat is reduced.

3. For drying of meat after softening it, my family members were expending more fuel than it

usually required. What was the problem? They used to close more portion of head of vessel. But

I observed the evaporation phenomena, as the vapour pressure of steam is higher than the vapour

pressure of moisture in the atmosphere due to which the diffusion of vapour takes place from

higher concentration of top free surface of liquid inside the vessel into the atmosphere. Hence if i

unclosed the vessel, the rate of diffusion increases due to increase in area exposed to atmosphere

which results in less consumption of fuel
