Decomposition of Deterministic Unsteadiness in a Centrifugal Turbomachine: Nonlinear Interactions Between the Impeller Flow and Volute for a Double Suction Pump
(The American Society of Mechanical Engineers (ASME), 2011)Modern designs for centrifugal pumps consider flow unsteadiness as a main concern. The averaged impact of blade to blade structures and impeller-tongue or impeller-diffuser interactions is considered ... -
Experimental and Numerical Investigations of a Turbulent Flow Behavior in Isolated and Nonisolated Conical Diffusers
(The American Society of Mechanical Engineers (ASME), 2011)In some industrial processes, and especially in agrofood industries, the cleaning in place mechanism used for hydraulic circuits plays an important role. This process needs a good knowledge of ... -
Discussion: “A Novel Explicit Equation for Friction Factor in Smooth and Rough Pipes” (Avci, A., and Karagoz, I., 2009, ASME J. Fluids Eng., 131, p. 061203)

Unsteady Numerical Simulation of Cavitating Turbulent Flow Around a Highly Skewed Model Marine Propeller
(The American Society of Mechanical Engineers (ASME), 2011)The cavitating flows around a highly skewed model marine propeller in both uniform flow and wake flow have been simulated by applying a mass transfer cavitation model based on Rayleigh–Plesset ... -
Synergy of Resistance Reduction Effects for a Ship With Bottom Air Cavity
(The American Society of Mechanical Engineers (ASME), 2011)Friction on a surface covered by an air cavity is much less than friction in water but there is a resistance penalty caused by the cavity tail oscillations. Nevertheless, there is a method ... -
Spectral Method for Analyzing Motions of Ellis Fluid Over Corrugated Boundaries
(The American Society of Mechanical Engineers (ASME), 2011)A spectral method for solving the steady flow of a shear-thinning Ellis fluid is discussed for the case of a planar channel with corrugated boundaries. Polynomial approximations are employed ... -
A Combined Numerical and Experimental Study of Hydrodynamics for an Air-Water External Loop Airlift Reactor
(The American Society of Mechanical Engineers (ASME), 2011)The external loop airlift reactor (ELALR) is a modified bubble column reactor that is composed of two vertical columns that are interconnected with two horizontal tubes and is often preferred ... -
Head Curve of Noncavitating Inducer
(The American Society of Mechanical Engineers (ASME), 2011)In the inducer hydraulic design, one significantly important task is to estimate its noncavtating head; however, there is not a matured and reliable method for this presently. In this paper, ... -
Evaluation of Turbulence Models Using Direct Numerical and Large-Eddy Simulation Data
(The American Society of Mechanical Engineers (ASME), 2011)The performance of some commonly used eddy-viscosity turbulence models has been evaluated using direct numerical simulation (DNS) and large-eddy simulation (LES) data. Two configurations have been ... -
