Fluid flow emerges with high velocity referred as liquid jet. Water Jet having its applications in many fields includes agriculture and power generation it has been widely utilized. Impact value of the jet is highly important, to generate maximum efficiency operation. Many factors influence impact depends on type vane used such as: Flat, hemispherical, curved etc. The aim this work investigate ...

Turbine guide vanes are among the most critical and complex turbine parts. As an entire engine comprises a significant number of vanes, simplification measurement process translates into overall time money savings. The key to is define areas for inspection, which enables relaxation strict inspection standards in all stable manufacturing. method described herein can help engineers achieve saving...

High-thermal performance PWR (pressurized water reactor) spacer grids require both low pressure loss and high critical heat flux (CHF) properties. Numerical investigations on the effect of angles and position of mixing vanes and to understand in more details the main physical phenomena (wall boiling, entrainment of bubbles in the wakes, recondensation) are required. In the field of fuel assembl...

Stall usually occurs in the hump area of head curve, which will block channel and aggravate pump vibration. For centrifugal pumps with guide vanes have a clocking effect, stall characteristic at different positions should be focused. In this paper, flow field under conditions is numerically simulated, rotor–stator interaction effects are studied. The double-hump found curve by using SAS (Scale ...

The problem we are dealing with is the following: find two sequences an and bn such that the average of the first bn triangular numbers (starting with the triangular number 1) is still a triangular number, precisely the an-th triangular number. We get also some side results: for instance one of the sequence instrumental to finding the asked for sequences turns out to be a bisection of the seque...
