)was

found close to the reticulo-omasal orifice. On sectioning, the

tumour mass was gelatinous with intervening fibrous septa.

Microscopical examination revealed unencapsulated mass

composed of various cellular parts and matrices. There were...

Spray nozzles are used in many applications such as cleaning, cutting and spraying. Spray nozzles come in many varieties and are usually classified according to the specific mode of atomization. This paper is focused on plain orifice nozzle...

Vortex formation is one of the serious problems in dam operation. In the present work, to study the vortex and its effects on orifice spillways of Karun III dam, two physical models were studied. A partial (with only one orifice) and comprehensive...

of pressure-swirl atomizers. In order to investigate the effects of orifice geometry and swirl angle on flow characteristics of simplex pressure-swirl injectors, several three-dimensional simulations were done. The effects of length to diameter ratio...
