Introduction:  A centrifugal pump essentially consists of an impeller rotating in a casing called volute. Fluid enters the eye (center) of the impeller and exits through the space between the impeller blades to the space between the impeller and casing walls. The velocity of fluid elements is in both tangential and…

Introduction: An air flow bench is a device used for testing the internal aerodynamic qualities of an engine component and is related to the more familiar wind tunnel.  The  Mass flow rate is defined as the rate of movement of liquid mass through a unit area. The mass…

Introduction Computational fluid dynamics ( CFD) is a branch of fluid mechanics that analyzes and solves problems involving fluid flows using numerical analysis and data structures. CFD applies to a broad variety of research and engineering problems in many fields of study and industry including aerodynamics and aerospace…

INTRODUCTION Airfoil, shaped surface, such as an airplane wing, tail, or propeller blade, that produces lift and drag when moved through the air. An airfoil produces a lifting force that acts at right angles to the airstream and a dragging force that acts in the same direction as the airstream. The lift…

Introduction: Piston assembly consists of a piston, piston rings, and gudgeon pin. It transmits to the connecting rod and crankshaft the gas force produced during combustion. As the piston is attached by means of a gudgeon pin to the small end of the connecting rod. As gas force is transmitted it guides the connecting…

IC Engine Valve Train A valve train is a mechanical system that controls intake and exhaust valve operation within an internal combustion engine. The intake valves control the flow of air/fuel mixture (or air alone for direct-injected engines) into the combustion chamber, while the exhaust valves control the flow of exhaust…

Planetary Gear: An epicyclic gear train (also known as planetary gear) consists of two gears mounted in such a way that one gear's center rotates around the center of the other. A carrier links the centers of the two gears and rotates around the other, called the sun gear or sun ring, to hold one gear, called the earth…

  INTRODUCTION Geneva mechanism, also known as Geneva Stop, is one of the most widely used methods for the development of irregular rotary motion, distinguished by alternating motion and rest periods with no spatial reversal. This is often used for indexing (i.e., rotation around a specified angle of a shaft). Application…

INTRODUCTION Frequency response analysis in Finite Element Analysis (FEA) is used to calculate the steady-state response due to a sinusoidal load applied to a structure at a single frequency. The goal of modal analysis in structural mechanics is to determine the natural mode shapes and frequencies…

AIM: Try to understand the concept of genetic algorithm.  To write a code in MATLAB to optimise the stalagmite function and find the global maxima of the function. Plot graphs for all 3 studies and for F maximum vs no. of iterations. Genetic Algorithm: A genetic algorithm makes uses of techniques inspired…
