The usage of splitter blades to enhance the performances low specific speed pumps is common practice. Based on experimental and numerical studies, influence addition one two investigated a very pump assess their impact not only performance characteristics but also losses in all domains. First, main characteristic curves are discussed it shown that enhances head while impairing its efficiency. S...

objectives: geographic tongue or migratory glossitis is an inflammatory disorder with unknown etiology. considering the accompanied burning pain, taste dysfunction, and lack of definite cure, it is important to treat this condition symptomatically. the objective of the current study was to compare the efficacy of a combination of 0.05% retinoic acid and 0.1% triamcinolone acetonide with that of...

Centrifugal pumps are divided into two main components, namely the impeller and volute. The is a rotating pump component, while volute stationary component. current problem in industrial world that capacity operates not accordance with written so does work optimally. In addition, structural analysis of minimally carried out damage to often occurs. To overcome this, it necessary analyze performa...

The fluid dynamics of the Thoratec HeartMate III (Thoratec Corp., Pleasanton, CA, U.S.A.) left ventricular assist device are analyzed over a range of physiological operating conditions. The HeartMate III is a centrifugal flow pump with a magnetically suspended rotor. The complete pump was analyzed using computational fluid dynamics (CFD) analysis and experimental particle imaging flow visualiza...
