Abstract:

Hydraulic turbine suction pipes at hydropower plants (HPPs) play an important role for providing high power indices of HPP operation. At the same time for channel type HPPs with vertical reactive hydraulic turbines curved large size suction tubes are used and this leads to great costs for their installation. That is why the significance of economic analysis for justification of the size of such suction pipes is underlined. Minimally possible sizes of curved pipes (height and length) are determined by hydraulic turbine normal operation requirements and are given in reference books. Nevertheless

Abstract:

The pumping station is widely used in our modern life. The occurrence of the vortex at pumpsump, which is causing air entering pipe intake, is a common problem in the design of pumps. Thisphenomenon, including surface and sub-surface vortex, may lead to damage to the pumping structure, highpower consumption, and loss in pump performance. In some requirements, the multiple suction pipes areusing to get the required flow. Due to this arrangement, the performance of the suction pipes will influence.This paper is aimed to investigate the occurrence of vortices around the flow pattern of two pumps

The pumping station became widely used in many fields. Free surface vortices at intakes of pumps are not favorable. It may cause noise, excessive vibration, damage to the pumping structure, reduction in efficiency and flow for hydro-turbines, etc. One of the important problems encountered during the pump intake design is the depth of submergence and other design parameters to avoid strong free-surface vortices formation. This study aims to compute the critical submergence depth with some geometrical and hydraulic limitations by using Computational Fluid Dynamic (CFD) package. The mathematical

In this study the origins of premature transition due to oversuction in boundary layers are studied. An infinite row of circular suction pipes that are mounted at right angles to a flat plate subject to a Blasius boundary layer is considered. The interaction between the flow originating from neighbouring holes is weak and for the parameters investigated, the pipe is always found to be unsteady regardless of the state of the flow in the boundary layer. A stability analysis reveals that the appearance of boundary layer transition can be associated with a linear instability in the form of two uns

Abstract:

The use of suction caissons (suction piles) in marine environments has been increasing in the last decade. A suction caisson is a steel pipe with an open bottom and a closed top that is inserted into the ground by pumping water out of it. Pumping creates a differential pressure across the caisson's top that pushes it into place, thus eliminating the need for pile driving. There are a number of uncertainties in the design of suction caissons. First, the state of stress and soil conditions adjacent to a suction caisson differs from those around typical driven piles or drilled shafts. Second, the

The 101-JTC condenser tank has excess steam condensate due to the addition of admission steam from 101-JT. Therefore, it is necessary to design a piping system that connects 101-JTC condenser tank with the 112-JB pump to drain the condensed excess steam. The designed piping system will encounter a dynamic response caused by fluid flow fluctuation over the time. This dynamic response causes the pipe to experience stress. To find out the resulting voltage which will not cause damage or failure, it is necessary to estimate the safety factor in a piping system that has been given static and dynami

The effects of wall suction on the structure of fully developed pipe flow are studied numerically by solving the Reynolds averaged Navier-Stokes equations.

Computed results are compared satisfactorily against experimental measurements. Analytical results, based on boundary layer assumptions and the mixing length concept, provide a law of the wall for pipe flow under the influence of low suction rates.

Abstract:

Diesel engine is one type of piston motor fuel, whose fuel combustion occurs due to high air pressure in the combustion chamber. The combustion process diesel engine generates heat energy and raises the high pressure in the cylinder, the pressure is comverted to mechanical energy on the crankshaft. Then the cooling system is needed on the main engine. The cooling system is one system that functions to maintain the engine temperature at a certain temperature in accordance with the design specified so that the diesel engine can operate sustainably. This research work aims to find out how to work

Abstract:

The results of experiments on the flow through a circular sudden expansion pipe at moderate Reynolds numbers are presented. At five diameters upstream of the expansion, laminar flow was disturbed by a (constant) cross-flow jet, a suction or a (periodic in–out) synthetic jet from a hole in the wall. When the disturbance exceeded a critical value of the control parameter depending on the Reynolds number, localised turbulent patches formed downstream of the expansion at fixed axial positions. For the cross-flow jet, the onset of turbulent patches is related to the velocity ratio of the mean jet v

Abstract:

This work is concerned with the flow of a Newtonian fluid through a pipe of constant circular cross section which is uniformly porous. The governing unsteady equations are solved analytically after converting them to a third order ordinary differential equation using similarity transformation method. Expressions for axial and radial velocity components and pressure distribution are obtained. The characteristics of complex axial velocity and complex radial velocity for different values of parameters are analysed. The effects of small suction and small injection are delineated through graphs. Re

Abstract:

The efficiency of a modified Boulton suction sampler was tested in 2 riffle zones, using multiple removals. Macroinvertebrate fauna was sampled with approximately 70% efficiency on first removal, while organic matter was sampled with 55% efficiency. Sampling efficiencies for specific taxa ranged from 86% (Plecoptera) to 66% (Chironomidae) and 59% (Trichoptera). The results of this study indicate that sampling efficiency can be improved either by taking multiple samples at one location or by increasing the time spent disturbing the substratum and pumping water from the stand pipe. The results a
