- Direct Numerical Simulation of Transition in Pipe Flow. Have developed a DNS code to simulate pipe flow transition with the spectral element method. In case of smooth pipe flow, two types of transitional structures named as 'turbulent puff' and 'turbulent slug' were simulated as a result of prescribed local disturbance. In case of rough pipe flow, the distributed wall roughness was simulated by blowing and suction of fluid on the wall.
