The present study focuses on finding an economic design of nozzles used in water discharge lines. An analytical solution is reached for computing the pipe-nozzle diameter ratio achieving minimum pipe cost using derivative method. derived equation shows that at a particular ratio, CP minimum. However, this evident from worked illustrative example. On comparison basis between and conventional one...

Recent determinations of the Newtonian constant of gravity have produced values that differ by nearly 40 times their individual error estimates (more than 0.5%). In an attempt to help resolve this situation, an experiment that uses the gravity field of a one-half metric ton source mass to perturb the trajectory of a free-falling mass and laser interferometry to track the falling object was perf...

The mixing characteristics of coolant air jets with the hot gas exiting the gas turbine combustor’s primary zone is of major importance to the combustor exit temperature profile. In the present work, a three dimensional numerical simulation on the basis of the finite volume method was developed. The aim was to investigate the penetration and mixing characteristics of directly opposed rows of co...

Flip buckets are terminal spillway elements, generating free jets for energy dissipation. Deflectors are an alternative to flip buckets with constructional ease yet of similar hydraulic features. A first experimental study published at the 33 IAHR Congress, Vancouver, investigated deflectorgenerated jets in terms of their air concentration characteristics. For jet impact onto a movable bed, the...

The capillary instability of liquid crystalline (LC) jets is considered in the framework of linear hydrodynamics of uniaxial nematic LC. The free boundary conditions of the problem are formulated in terms of mean surface curvature H and Gaussian surface curvature G. The static version of capillary instability is shown to depend on the elasticity modulus K, surface tension σ0, and radius r0 of t...

The flow and acoustic fields of jets at a Mach number 3.1 impinging on plate the jet nozzle exit, where is diameter, have been investigated using highly resolved large-eddy simulations. perforated with hole diameter , or . full-plate free-jet cases also considered. pressure levels are highest for non-perforated decrease as increases. Compared free jet, they higher by about 5 dB full plate, 4 3 ...
