Abstract: This paper reports numerical investigation concerning the interaction of a laminar methane–air counterflow diffusion flame with monodisperse and polydisperse water spray. Commercial code ansys fluent with reduced chemistry ...

Abstract: A numerical study has been performed in an axisymmetric diffuser followed by a casingliner annulus of a typical gas turbine combustor to analyze the flow structure and pressure recovery in the geometry. Static pressure ...

Abstract: Numerical simulation employing different models is popularly used to predict spray combustion of liquid fuels. In the present work, we have compared the effects of three different combustion models, viz., eddy dissipation ...

Abstract: Atomization of fuel is a key integral part for efficient combustion in gas turbines. This demands a thorough investigation of the spray characteristics using innovative and useful spray diagnostics techniques. In this work, ...

Abstract: A critical issue in design and operation of combustors in gas turbine engines is mitigation of thermoacoustic instabilities, because such instabilities may cause severe damage to the mechanical structure of the combustor. ...

Abstract: This work investigates natural convection in an enclosure with localized heating on the bottom wall with a flushed or protruded heat source and cooled on the top and the side walls. Velocity field measurements are done by ...

Abstract: Experimental and numerical analyses are carried out for a natural circulation loop (NCL) under low and moderate heater power. The effect of ambient temperature variation on the loop thermal behavior has been taken into ...
