The effect of flow deflection is observed in term of stagnation pressure region located somewhere around 45 degrees from the flow direction and in is good agreement with the present experimental results and RMS, K-wSST, DES (SST-LES), SST-Cas, K-epsilon and LES results obtained from previous study conducted by Afgan .
The alternating mode of the stagnation pressure is obtained again.
The position of the stagnation pressure region is located somewhere around 45[degrees].
The stagnation pressure coefficient and drag coefficient also show a complex dependence on the power law index and Reynolds number.
8; (ii) to obtain accurate results by systematically varying the value of the Reynolds number to check whether the results do show a monotonous variation thereby facilitating interpolation of the results; (iii) to consolidate the results in the form of predictive expressions for stagnation pressure coefficients, drag coefficient, etc.
These, in turn, can be used to infer the values of the macroscopic parameters (individual and total drag coefficients) and the other parameters like the separation angle, recirculation length, stagnation pressure and surface vorticity.
This means that the dynamic equilibrium is re-established when the stagnation pressure from inside the tower equals the one from outside, at the exit level,
The Bernoulli equation is used to retrieve the stagnation pressure of the escaping air above the tower, under incompressible conditions
5] from (35) and for the density ratio from (23) and (32) are now used to write the full expression of the stagnation pressure in "6" as
The stagnation pressure and temperature are computed using the formulas
The Stage 1 stagnation pressure is measured using a Paroscientific (3) Model 740 with a full scale of 1400 kPa.
