Parametric study of cone angle influence on bubble vortex breakdown onset in laminar conical flow at various swirl numbers

Convective Heat Transfer from a Heated Rotating Disk at Arbitrary Inclination Angle in Laminar Flow

In this paper, experimental data and numerical results of heat transfer from a heated rotating disk in still air are presented over a large range of inclination angles and a dimensionless correlation is developed for forced, natural and mixed convection. The measured Nusselt number over the rotating disk is compared with the numerical results. The goal of the present research is to develop a se...

Parametric study of vortex structures and their dynamics in swirl-stabilized combustion

The dynamics of major flow structures were studied in a gas turbine model combustor for perfectly premixed swirlstabilized flames under a variety of reacting and non-reacting conditions using high-repetition-rate laser diagnostics. The studied combustor is a target case for the International Workshop on Advanced Measurement Techniques and Computational Methods for Premixed and Partially Premixe...

Experimental study of the effect of the trashrack on the vortex at the intake of the hydroelectric power plants in various flow rates and submergence depths

One of the main problems commonly encountered by the intakes of the power plants is the formation of vortex and turbulent flow at the intake of the reservoirs.Using the image processing method by using the PTV technique in a survey flow hydraulic of a horizontal intake with a trashrack by certain opening,under the submergence depths and different flow rates and comparing it with intakes without...

Investigation of Bubble Size Distributions in Oscillatory Flow at Various Flow Rates

The demand for eco-friendly technologies for industrial processes is increasing. Various factors such as labour costs, exploitation and waste management influences the production costs and hence the profit generated. The water treatment industry is one example of a well-developed sector which is facing these concerns. Microbubble techniques exhibit many benefits which make them applicable to he...
