AIM:  To run a pipe flow simulation with an inlet Reynolds number of 100,1000 and 10,000. THEORY: Fluid Flows can be classified into various types. They are: (i) Steady and Unsteady Flow. (ii) Uniform and Non-Uniform Flow (iii) Incompressible and compressible flow (iv) Laminar and Turbulent Flow Laminar Flow:…

AIM: To model the flow over a NACA0017 airfoil for the angle of attacks 0,2,4,6,8 and 10 degrees and compare their lift and drag forces. THEORY: An airfoil is the cross-sectional shape of a wing, blade(of a propeller,turbine and a rotor) or a sail. An airfoil-shaped body moving through a fluid produces an aerodynamic force.…

AIM:  To simulate the flow over a cylinder for the conditions shown in the video, increase the Reynolds number by 20%, 40% and 100% and create animations for Pressure and Velocity variation. THEORY: Internal and External Flow: The flow of an unbounded fluid over a surface is treated as ‘external flow'…

AIM: To create a 3D model of a flow bench and run flow analysis, plot lift vs mass flow rate, and perform grid dependence test. THEORY: An Air-Flow Bench is a device that measures the volume or mass of air that will pass through a bounded path or conduit in relation to an applied pressure differential. The pressure differential…

AIM: To obtain the relationship between Pressure ratio and outlet mass flow rate in a centrifugal pump. THEORY:   What is a Centrifugal Pump? A centrifugal pump is a mechanical device designed to move a fluid by means of the transfer of rotational energy from one or more driven rotors, called impellers. …

AIM:  To use the following 2D CAD drawings to create the 3D model of the internal Geneva mechanism and get the results for the above cases.   THEORY: Geneva mechanism, also known as Geneva Stop, is one of the most commonly used devices for producing intermittent rotary motion, charectized by alternate periods…

AIM: To use the given inputs and design planetary gears.   THEORY: Basic Terminologies: (i)Spur Gears: They type of gears whose teeth are cut parallel to the axis of the shaft. (ii)Velocity Ratio: Velocity ratio is the ratio of the angular velocity of the driving gear to the angular velocity of the driven gear. (iii)Pitch…

AIM: To model piston assembly and run motion analysis for the following cases: (i) 0mm wrist pin offset. (ii) 10mm wrist pin offset. (iii) -10mm wrist pin offest.   THEORY: An IC Engine is that kind of prime mover which converts chemical energy of fuel to mechanical energy. The fuel on burning changes to gas which…

AIM: To model the parts of a valve train, assemble them and run the simulation using the below parameters:  THEORY: Valves are mechanical control elements needed to admit fresh charge and allow the burnt gases to escape out of the cylinder. Two valves, an inlet and an exhaust, are used for this purpose. Fresh mixture…
