The design of combustors in propulsion systems remains a significant technical challenge. The advent of computational fluid dynamics (CFD) has significantly reduced the human effort per design cycle and also the number of cycles involved. CFD can be used as a tool to simulate reacting flows inside both simple and complex combustor geometries for a wide range of fuel-oxidizer mixtures.
OBJECTIVES
-
CFD simulation it carried out to validate the design of combustion chamber based total pressure recovery.
-
To check the recirculation zone (primary zone) which acts as flame holder also to check penetration in throughout the combustion chamber

Aircraft store separation
The carriage and release of stores from fighter aircraft are of primary importance to the Air Force. Accurate prediction of the trajectory of a store released from an aircraft is critical in assessing whether the store can be released safely as well as if it will accurately reach its target.
OBJECTIVES
-
To Predicting the trajectory of angular orientation, angular velocity and distance of the store.

Turbo machinery
Centrifugal compressors are still used in small engines of aircraft due to their high compressor ratio and narrow installation space compared to axial-type compressors. In many industrial centrifugal compressors are also still widely used. Most turbochargers in vehicles adopt a centrifugal-type compressor.
OBJECTIVES
Centrifugal compressor surge and stall are an instabilities flow and system phenomenon, which can lead to a loss of engine power, large pressure transients and, in some cases, failure of the compressor and bearing system. To study the development of numerical models aiming at fault-free detection of the surge margin.
-
Develop and test control strategies for a centrifugal compressor
-
Using CFD explore and understand compressor stall and surge.
-
Develop and test control strategies for given centrifugal compressor.
-
Apply CFD to compare low speed and hing-speed configurations using Software.

Biomedical Engineering
The aortic aneurysm is modeled as a 3D model using MIMICS software from the CT scan data. A functional analysis of this model is performed using Computational Fluid Dynamics. Hence both MIMICS and CFD can together act as a tool to understand the formation and deposition of the plague particles in an aneurysm and to study the hemodynamic characteristics.
OBJECTIVES
-
To consider Thoracic Aortic Aneurysm and to create a 3D model.
-
To study the blood flow velocity, wall shear stress and blood pressure at the thoracic aortic aneurysm region using Computational Fluid Dynamics.

Structural analysis of a composite continuous girder
Use of concrete in various forms has become an intreresting research topic in recent years due to the increase in need for construction based on various environmental conditions. Porous structured concrete design has been used widely as it can solve various factors affecting the concrete with standability.
OBJECTIVES
-
To analyze the deflection in the steel section and internal stresses in the concrete slab for continuous composite girders with the single, double and three rectangular opening in the steel web.
