초록정보

The present study has been carried out to develop a correlation of two-dimensional cascade with DCA blade profile by numerical simulation. Numerical simulation result has been achieved with the solution of the direct cascade problem using the FLUENT. The cascade configurations were determined by various combinations of an inlet blade angle ($\beta′_1=50, 60$, and 70 degree), blade thickness(t/c=0.06 and 0.1), camber angle (θ=0, 10, 20, 30, and 40 degree), and cascade solidity (σ=0.75, 1.0 and 1.5). For each configuration, simulation results were obtained for total pressure loss coefficient, deflection angle and deviation angle as a function of incidence angle. The Reynolds number based on the chord and the inlet absolute velocity were fixed at $5\times10^5$. The calculated incidence, deviation and deflection angles corresponding to the point of minimum total pressure loss were correlated. The derived correlations have been compared successfully to the NASA DCA cascades experiment. It was found that the deflection is independent of the blade thickness(t/c).
