‎The water wave generation by wave paddle and a freely falling rigid body are examined by using an Incompressible Smoothed Particle Hydrodynamics (ISPH)‎. ‎In the current ISPH method‎, ‎the pressure was evaluated by solving pressure Poisson equation using a semi-implicit algorithm based on the projection scheme and the source term of pressure Poisson equation contains both of divergence free ve...

The article considers a variant with the operation of spillway No. 2 Boguchanskaya HPP as main structure for period temporary hydroelectric complex. In process developing options skipping construction costs, calculation was made throughput free overflow through flat threshold at level 167.0m FSL=175m and forcing UVB to 185.0 m damping flow energy in water well. task calculations is obtain disch...

we demonstrate that photothermal deflection spectroscopy can be used to measure velocity distributions in dye jets. such measurements are useful in determining the quality of flow in dye jets, the quality of jets is very important for a stable and naanow linewidth operation of dye lasers
