Numerical study of the separation point for external flows
In this paper Numerical simulations are performed using the control volume method to obtain separation point of two-dimensional laminar, steady, incompressible flows. Low Reynolds number flows over cylinder, NACA 0012 and ...
Proposed kinematic model for fish-like swimming with two pitch motions
In the present investigation a new kinematic model for a fish-like swimming is presented. In this model the foil has two rotational motions in order to approach of the fish swimming performance. This kinematic model is a generalized model...

Investigations on optimization of kinematics parameters of oscillating foil for energy extraction from tidal current flows
In present work, effect of different kinematics parameters on oscillating foil energy extraction is numerically investigated. It is noted that velocity of oscillating foil relative to free stream velocity (Tip Speed Ratio) has significant effect...
The measurements of thermal neutron flux distribution in a paraffin phantom
The term ‘thermal flux’ implies a Maxwellian distribution of velocity and energy corresponding
to the most probable velocity of 2200 m s−1 at 293.4 K. In order to measure the thermal
neutron flux density, the foil activation method...
