Otto Cycle

Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid. The pressure rises in three stages: 1. Fluid enters axially through eye of the casing, is caught up in the impeller blades, and is whirled tangentially and radially outward until it leaves…

A flow bench is a device used for testing the internal aerodynamic qualities of a component of an engine, primarily for testing the intake and exhaust ports of cylinder heads of IC engines. For this project, a 3D model of a flowbench was created and flow analysis was performed for three grids. On deciding…

Re = ρ*U_inlet*D/μ D = cylinder diameter = 0.1 μ = dynamic viscosity=1.8205 ρ = Fluid density=1.2047 For initial inlet velocity of 1m/s Re=1.2047*1*0.1/1.8205=0.06617 Length of domain = 2.3 m Simulation end time is a little over 2 times the flow thorugh time. Velocity: Pressure:   for  20% increment…

Airfoil shapes developed by the National Advisory Committee for Aeronautics (NACA) are called the NACA airfoils. An airfoil is the cross-sectional shape of a wing, blade, or a sail. The lift coefficient, CL = 2*FL/(ρ*u*u*A) FL=lift force; ρ= fluid density; u= relative fluid incoming speed; A= relevant…

The rankine cycle is a model used for steam turbine systems commonly found in thermal power generation plants. The processes in boiler and condenser are isobaric. The processes in turbine and pump are assumed to be isentropic (this is not the case in reality). Standard Xsteam library was used to get the steam table data…

To normalize the plots, the graphs were exported to excel and all the velocities were didvided by their respective inlet velocities. Reynolds number (RN) = fluid velocity (u)* Inside diameter of pipe / kinematic viscosity (v) v = 1.5111*10^-5, at 293 K from http://theengineeringmindset.com/properties-of-air-at-atmospheric-pressure/…

The code firsts reads the file. When the pointer reaches the first data row, the code will start the main extraction work and will arrange the parameters in a 112*7 matrix, with odd rows containing high temperature coeffs and even rows containing low temperature coefficients. It stores parameters in the matrix and adds…

1.) Genetic Algorithm is an optimization technique to find the minimum of the solution. It is more suited to solve non smooth functions, since there are other solvers which take less time than GA to solve smooth or relatively less complex problems. One major advantage with GA is that it canbe used for all types of problems…
