INTRODUCTION Ahmed body is the model replicating body of a generic car or utility vehicle. This model was developed by S.R.Ahmed for his research named \"Some Salient Features of the Time-Averaged Ground Vehicle Wake\" in 1984 [1]. Now, this model is used as the baseline model for the flow analysis by the automobile industries…

Introduction Combustion is burning of fuel in the presence of oxidizer to give species: CO2, H2O and NOx and large amount of heat is generated. Possible types of combustion simulations can be categorized based on the mixing of air and fuel mixture and based on phase. Based on mixing of air and fuel mixture: (i)Non-Premixed…

INTRODUCTION Mixing tee is used for mixing two different flow streams to form the gradients of the combined flow stream. One of the major application is in air conditioning systems and in hot water systems for household purposes. In this report, a computational model is developed to investigate the mixing effectiveness…

Introduction Cyclone separator is a device that employs a centrifugal force generated by a spinning gas stream to separate particles from the carrier gas. Their simple design, low maintenance costs, and adaptability to a wide range of operating conditions such as sizes and flow rates make cyclone separator one of the most…

INTRODUCTION Conjugate Heat Transfer(CHT) is the combination of heat transfer in solids (where conduction is dominant) and heat transfer in fluids (where convection is dominant). CHT analysis is done whenever there is heat transfer between a solid body and fluid flow. A simple example of CHT analysis is a hot body immersed…

INTRODUCTION Flows with the free surface are important in many industrial systems including nuclear power plants, oil industry and other fields of process engineering[1]. Appropriate modeling of the free surface flows is important also for the understanding of some basic phenomena in fluid dynamics like Rayleigh-Taylor…

Introduction In gearbox for the smooth running of gears and to increase the lifetime of gears, lubrication is required. The lubricant reduces the friction at the contact between the mating gears which increases the lifetime of gears. So for this, the lubricant should be properly provided to all the teeth of the gears.…

  Introduction Analysis of flow around a cylinder is necessary as the flow patterns for some range of Reynolds numbers, the body may undergo structural vibrations due to vortex shedding. Vortex shedding is an oscillating flow that takes place when a fluid flows past a body at a certain range of Reynolds number which…

INTRODUCTION Gate Valve is used to control the mass flow rate in a pipe. For different lifts of the valve, there will be a different mass flow rate at the outlet. To obtain the mass flow rate at different lifts a CFD simulation can be performed. The geometry used for the simulation is shown below:   The simulation…
