Interaction between free-stream turbulence and tip-vortices of wind turbine blades with and without winglets
(IOP Publishing, 2018)
Experimental investigations of the free-stream turbulence impact on the tip-vortices generated in wind turbine blades have been performed. The investigation is done by exposing an efficient laboratory scale wind turbine ...
Active-grid turbulence effect on the topology and the flame location of a lean premixed combustion
(Society of Thermal Engineers of Serbia, 2018)
Lean premixed combustion under the influence of active-grid turbulence was computationally investigated, and the results were compared with experimental data. The experiments were carried out to generate a premixed flame ...
Characterization of turbulence generated by an active grid with individually controllable paddles
(Springer, 2018)
An active grid with individually controllable paddles was constructed to generate strong turbulence (Reλ>200). Measurements of turbulence quantities using the hot-wire technique were conducted in a wind tunnel along the ...
Application of giesekus model for capillary extrusion of rubber compound
(The Society of Chemical Engineers, 2019-02)
Extrudate swell is an important phenomenon occurring when high viscoelastic materials, such as rubber and rubber compounds, are extruded. In this work, the effects of relaxation time and relaxation mode on swell predictions ...
Predicting the performance of pressure-swirl atomizers
(Begell House Inc., 2018)
The purpose of this study is to evaluate the semiempirical correlations that are found in the literature by comparing them with all of the applicable experimental data that are also taken from the literature. Presentation ...
Numerical and experimental analysis of impinging synthetic jets for cooling a point-like heat source
(ASME, 2018-05-01)
High power light emitting diodes (LEDs) being used for low and high beam in automotive lighting need active cooling of their heat sinks by radial or axial fans. But the moving elements of the fan cause abrasion, noise, and ...
Numerical and experimental analysis of the flow and transition of free synthetic jets
(IOP Publishing, 2019-04)
In this paper, flow characteristics and the transition of synthetic jets are investigated numerically and experimentally. The investigated synthetic jets have a dimensionsless stroke length L-0/d of 146 and 167, an U-0 of ...
Effects of turbulence intensity and length scale on the flame location of premixed turbulent combustion in a diffuser combustor
(J-STAGE, 2017)
This study focused on the dependency of the flame location of a premixed propane-air flame on turbulence intensity and length scale. The flame location was investigated using a diffuser-type combustor to show the response ...
A design and optimization method for matching the torque of the wind turbines
(AIP Publishing, 2015)
An aerodynamic shape optimization method for a horizontal axis wind turbine is developed and verified through experimentation with a laboratory-scale wind turbine. Our method is based on matching the rotor's and the coupled ...
Numerical investigation of multiphase flow inside a pressure swirl atomizer at the initial stage of injection
(Begell House Inc., 2018)
Pulse-mode operating atomizers are widely used in industry. This paper presents the fluid flow details and characteristics inside a pulse-mode operating pressure swirl atomizer (PSA). Transient flow simulations are performed ...
