Development of a solver based on the blade element theory

Objective: Simulating a sphere pressing a flat plate and observing the plastic deformation in the plate. When the sphere is pressed onto the plate, the plate material will yield under the force applied on it due to the sphere being pressed into it. Once the sphere is retracted, the plate will undergo minute elastic spring…

Objective: Simulating the bending of a wire made of different materials and comparing the stress and strains developed in the wire. Materials: The wire materials compared are copper alloy, aluminium alloy and magnesium alloy. All of these are taken as non-linear material models (bilinear isotropic hardening models) so…

Objective: Simulating the rolling process of a copper alloy sheet between two steel rollers. Rolling is the process where a sheet is plastically deformed due to forces applied by two rollers and is a form of cold working process, i.e. plastic deformation is carried out below the recrystallization temperature of the sheet…

Objective: Computational modelling and stress analysis of weld joints for their verification in a component and comparing the results for different weld materials. Simulation parameters: Mesh: Since we want to verify the weld joints in the component, the mesh on the welds should be refined. The weld mesh is refined using…

Objective: Carrying out a finite element simulation for the bending of a sheet using a punch (or ram) and a die and calculating stress and strain produced on sheets of different materials and in different simulation parameters. Modelling: In a sheet bending process, the sheet is placed on a die, which has a valley like…

Objective: To simulate the rotational movement of a rail wheel on a track and to analyse the stress and strain developed in the system for varying bearing loads. Modelling of the rail wheel track:The modelling and setup in ANSYS is carried out assuming the axle doesn't rotate but the wheel does and a bearing is present…

I have attempted my independent research project on the topic of blade element theory for determining the performance characteristics of a propeller. I have used MATLAB to develop a solver which uses blade element theory to calculate how a propeller with a particular airfoil section will perform aerodynamically. I have…

Grid dependency test: It is a type of parametric study of a finite element model where the variation of the analysis results is observed with respect to changing mesh refinement (i.e. reducing mesh element sizes). In other words, the dependency of the FE analysis on the mesh applied is studied. At the point where the FE…

Rankine Cycle: Rankine cycle is a thermodynamic cycle and an example of a vapour power thermodynamic cycle; a cycle which uses water, in both its liquid and gaseous states, to generate power. The rankine cycle has 4 major components: Steam Turbine: The primary power generation unit of the rankine cycle. Steam enters the…

The NASA thermodynamic data file is a collection of various coefficient values for thermodynamic equations defined for 53 different chemical species. The thermodynamic equations are given by: Cp/R = a1 + a2 T + a3 T^2 + a4 T^3 + a5 T^4 H/RT = a1 + a2 T /2 + a3 T^2 /3 + a4 T^3 /4 + a5 T^4 /5 + a6/T S/R = a1 lnT + a2 T +…

GENETIC ALGORITHM: The genetic algorithm is a method for solving both constrained and unconstrained optimization problems that is based on natural selection, the process that drives biological evolution. The genetic algorithm repeatedly modifies a population of individual solutions. At each step, the genetic algorithm…

ABSTRACT: This project report discusses the designing and development of a test rig which can be used to study the vibrational characteristics of a beam. Using this test-rig, the main objective of this project is to study the transverse vibrations of flexible beams when subjected to eccentric rotating mass excitations.…

A simple pendulum consists of a mass m hanging from a string of length L and fixed at a pivot point P. When displaced to an initial angle and released, the pendulum will swing back and forth with periodic motion. By applying Newton's secont law for rotational systems, the equation of motion for the…

The air-standard-Otto cycle is the idealized cycle for the spark-ignition internal combustion engines (or the petrol engines). This cycle is shown below on p-v and T-s diagrams. The Otto cycle 1-2-3-4 consists of following four process:Process 1-2: Reversible adiabatic compression of air.Process 2-3: Heat addition at constant…

Any object moving through a fluid experiences drag - the net force in the direction of flow due to pressure and shear stress forces on the surface of the object. The drag force can be expressed as: Fd =  1/2 cdρ v2 A                       where…

NOTE: Here 2 cases are discussed, 1). If we want the trunk lid to stop and not move after the first contact with the trunk 2). If we want the trunk lid to return back after stopping at the first contact with the trunk. For this simulation, it is important to know at which point of time and in what orientation the trunklid…
