A Prediction Tool For Spatially Decaying Freestream Turbulence
(CSME-SCGM, 2018-05)
A set of new correlation equations characterizing the spatial decay of isotropic homogeneous turbulence has been formulated in the current study. The correlation equations are based on the results from the current numerical ...
Dynamics Of A Free Pitching Flexible Cantilever Naca0012 Airfoil At Transitional Reynolds Numbers
(CSME-SCGM, 2018-05)
The dynamics of a free pitching flexible cantilever NACA 0012 airfoil were investigated at transitional Reynolds numbers. This work builds on previous investigations based on a quasi-2D rigid wing, moving elastically in ...
A Droplet Deformation And Fragmentation In A High Speed Air Jet
(2018-05)
Impingement of a gas jet on a suspended water droplet is modeled numerically. The jet velocity and jet diameter effects on the penetration length and the shape of the gas tunnel inside the droplet are studied. The gas ...
Water Droplet Impact And Spreading On A Narrow Gap
(CSME-SCGM, 2018-11)
The impact and spreading of a water droplet on a gap between two parallel plates has been studied experimentally. A deionized water droplet (2.03 mm diameter) impacted the plates at velocities of 0.06, 0.5, 1.0, and 1.5 ...
Estimation Of Shock Stand-Off Distance Using The Curved Shock Theory And Its Validation Via Numerical Modelling
(CSME-SCGM, 2018-05)
Curved shocks that are locally oriented normal to the direction of the pre-shock flow vector appear on bluff and blunt bodies in supersonic flow and at the center lines of axisymmetric air intakes. There have been numerous ...
A Model To Predict The Residual Layer Thickness In The Injection Molding Process
(CSME-SCGM, 2018-05)
The effects of the wall temperature on the residual layer thickness of the polymers are studied numerically in the filling process in the injection molding process. A lubrication approximation model is developed to furnish ...
Scaling And Machine Learning Analysis Of Turbulent Fluxes Of Momentum And Heat In The Microclimate Of An Urban Canyon
(CSME-SCGM, 2018-05)
Turbulent flow inside the urban roughness sublayer, despite its complexities, plays a crucial role in the microclimate of the built environment. The parameterization of flow in the urban roughness sublayer provides a better ...
Numerical Simulation Of An Over-Expanded Supersonic Nozzle Flow
(CSME-SCGM, 2018-11)
Flaring in oil and gas production is the controlled burning of unwanted exhaust gases to enhance safety. Obtaining complete combustion and thus eliminating or reducing smoke is critical to meet increasingly strict environmental ...
Effects Of A Channel Inclination On Displacements Of Viscoplastic Fluids
(CSME-SCGM, 2018-05)
The miscible displacement flow of a viscoplastic fluid by a Newtonian fluid is studied numerically and analytically in a near-horizontal 2D channel. We focus on a density-unstable flow configuration where the displacing ...
3D Dynamical Model For Liquid Sloshing Simulation In A Partially Filled Elliptical Tank
(CSME-SCGM, 2018-05)
Many of 2D mechanical models have been devel-oped to simulate liquid sloshing of a partially filled tank with different shapes. However, those models didn’t represent properly the complex liquid motion, especially in the ...
