Torque transport, mean velocity profiles and turbulent statistics of a wide-gap Taylor Couette flow
Wall-bounded turbulent flows that possess finite curvature of the mean flow streamlines are known to be starkly different from their plane counterparts. One of the primary distinguishing features of such flows is the ... -
Gust Rejection in Insect Flight
Large commercial and military aircraft can fly in turbulent wind conditions except in extreme weather events like cyclones. Smaller man-made vehicles like Micro aerial vehicles (MAVs) and Nano aerial vehicles (NAVs) are ... -
Heat Transfer and Visualization Studies in the Evaporator of a Flat Loop Heat pipe
Heat pipes are extensively used in spacecraft thermal control and electronics cooling for transfer of heat from high heat flux zones to low heat flux zones. The major advantage of heat pipe is it can transfer high heat ... -
