Cavitating venturies are one of the simplest devices to use on a flow line to control the flow rate without using complex valve and measuring systems. It has no moving parts and complex electronic systems. This simplicity increases the reliability of the venturi and makes it a superior element for the military and critical industrial applications. Although cavitating venturis have many advantages and many areas of use, due to the complexity of the physics behind venturi flows, the characteristics of the venturies are mostly investigated experimentally. In this study, venturi flows are investigated numerically and experimentally. Two-dimensional axisymmetric cavitating venturi flows are computed using a commercial flow solver FLUENT. An experimental study is then performed to assess the numerical solutions. The effect of the inlet angle, outlet angle, ratio of throat length to inlet diameter and ratio of throat diameter to inlet diameter on the discharge coefficient, and the oscillation behavior of the cavitating bubble are investigated in details.

Numerical and experimental investigation of flow through a cavitating venturi Yazıcı, Bora; Tuncer, İsmail Hakkı; Department of Aerospace Engineering (2006) Cavitating venturies are one of the simplest devices to use on a flow line to control the flow rate without using complex valve and measuring systems. It has no moving parts and complex electronic systems. This simplicity increases the reliability of the venturi and makes it a superior element for the military and critical industrial applications. Although cavitating venturis have many advantages and many areas of use, due to the complexity of the physics behind venturi flows, the characteristics of the ven...
Numerical investigation of cavitating flow in variable area venturi on the basis of experimental data Gümüşel, Hasan Tolg; Aksel, Mehmet Haluk.; Department of Mechanical Engineering (2019) Variable area cavitating Venturi is a throttling device that can regulate the flow rate used in liquid and hybrid rocket motors. It has a pintle mechanism which adjusts the flow area by moving back and forth in the direction parallel to the outflow from the Venturi. The flow rate is independent of the downstream pressure due to cavitation. This makes the variable area cavitating Venturi a very critical component for liquid propellant rocket engine because it can create an isolation between the inlet and the...
Incompressible flow simulations using least squares spectral element method on adaptively refined triangular grids Akdağ, Osman; Sert, Cüneyt; Department of Mechanical Engineering (2012) The main purpose of this study is to develop a flow solver that employs triangular grids to solve two-dimensional, viscous, laminar, steady, incompressible flows. The flow solver is based on Least Squares Spectral Element Method (LSSEM). It has p-type adaptive mesh refinement/coarsening capability and supports p-type nonconforming element interfaces. To validate the developed flow solver several benchmark problems are studied and successful results are obtained. The performances of two different triangular ...
Numerical simulation of transient turbulent flow in a heated pipe Uygur, Ahmet Bilge; Selçuk, Nevin; Oymak, Olcay; Department of Chemical Engineering (2002) A computational fluid dynamics (CFD) code based on direct numerical simulation (DNS) and the method of lines MOL approach developed previously for the solution of transient two-dimensional Navier-Stokes equations for turbulent, incompressible, internal, non-isothermal flows with constant wall temperature was applied to prediction of turbulent flow and temperature fields in flows dominated by forced convection in circular tubes with strong heating. Predictive ability of the code was tested by comparing its r...
Parameter study on tracer flow test Aydın, Hakkı; Akın, Serhat (2019-02-13) Periodic measurement of flow rate in production wells is essential to monitor performance of geothermal wells and reservoir. Tracerdilution method has been introduced as a reliable, cheap and environment friendly technique to measure mass flow rate and enthalpy intwo phase geothermal systems. In this study, Sodium Fluorescein is used to measure liquid phase mass flow rate in a two phase productionline and in a single phase liquid injection line. The study includes the effect of flow regime and flowrate on t...
