Computational Investigation of Drag Reduction by means of Two-Dimensional Roughness Element on the Suction Surface of an AirfoilBy Sitaram Nekkanti, Madhan Raj Harikrishnan, Muralikrishnan Arulkumar, Praveenkumar Jayakumar, Ram Prasath Veerapandian
Abstract: Computational investigation carried out to the effects of a two-dimensional roughness element placed on the suction surface of a zero camber airfoil of 1 m chord on its performance is presented. The roughness element was placed on suction surface of the airfoil at a distance of 30% from the leading edge of the airfoil. The roughness element was in the form of a wire. The diameter of the wire was …

Calibration And Comparison Of An Improved Rotatable Single Hole Probe In 4, 6 And 8 PositionsBy Sitaram Nekkanti, Rambabu Dara
Abstract: An improved single hole probe with a measurement volume of 0.3 mm dia. is developed in the present investigation. The probe is calibrated in a low turbulence open jet tunnel at a velocity of 50 m/s in yaw and pitch angle range of + 40 deg. at an interval of 5 deg. A special probe holder is developed so that the probe can be positioned at intervals of 15 deg. …
