We'll post an update here as soon as possible about the design including dynamic analysis and mechanical analysis. We appreciate any ideas to improve output energy efficiency, design and related analysis.
Thanks.

Dynamic Analysis for Wind Turbine Jet: Force Due to Velocity of the Wind

Wind Turbine Jet

At this moment, we try to do dynamic analysis for our wind turbine jet. Before we go through into the analysis, we must indentify first what are V1, V2, V3 and V4. The following symbols represent are:

V1 : Velocity of the wind away from the blades

V2 : Velocity of the wind just before the blades
V3 : Velocity of the wind just after the blades
V4 : Velocity of the wind away behind the blades

From the figure 1, we can assume that p1 = p4 and V2 =V3.

We also assume that between 1 and 2 and between 3 and 4 the flow is frictionless.

If you are more detail, you can ignore assumption and you can go to detail analysis. Generally between 1 and 2 and between 3 and 4 the flow are frictionless because of restriction in air is very small and we can neglect of their effect.

Therefore, we can apply Bernoulli equation.

From the substitution of equations above, finally we got the V2 equation such that.

We noticed that value of V2 is depending on V1 and V4. Absolutely in real life, we can only calculate value of V1 because of V4 value is depending on V1. So the conclusion is the higher output power generate by the wind turbine jet occur when the fast wind.

From the equation (2):
