Week 2 Air standard Cycle

Objective: Data visualization Compatibility check Basic performance calculation   The python code is attached below:   import matplotlib.pyplot as plt import numpy as np import math print("Please make sure that the CONVERGE data file is saved in the same path directory where Python code is saved") # Compatibility…

1. "popt" - It is an output of the function 'curve_fit'. It is the array that contains the optimum values of the coefficients of the cubic equation.    "pcov" - It is also an output of the function 'curve_fit'. It is a 2D array that contains the estimated covariance of the parameters in 'popt'. The…

 Simple Pendulum: The lenght of the pendulum is 1m, the mass of the ball is considered to be 1kg, and the damping coeff is 0.05. The time span under consideration is 0-20sec, which is sub divided into 150 points. The initial angular velocity is considered to be 3rad/s. So in the python code. Initial condition comprises…

Otto Cycle: The processes which take place in otto cycle are 1. process 1-2 - reversible adiabatic (Isentropic) compression. 2. process 2-3 - constant volume heat addition. 3. process 3-4 - reversible adiabatic (Isentropic) Expansion. 4. process 4-1 - constant volume heat rejection.   The Python code starts with defining…

The Finite Volume Method (FVM) is a discretization method for the approximation of a single or a system of partial differential equatons expressing the conservation, or balance, of one or more quantities. These PDEs are often called conservation laws. FVM uses a volume integral formulation of the problem with a finite…

1. Case 1 - Grading factor of 1   Editing the blockmesh file in the system folder, where the 'blockMeshDict' file is edited as per the domain vertices, blocks, the inlet, the outlet, the no slip conditioned wall and the other walls, which is shown below. /*--------------------------------*- C++ -*----------------------------------*\…

The main MATLAB code is below: close all clear all clc %Inputs n = 31; %No. of grid points gamma = 1.4; x = linspace(0,3,n); dx = x(2) - x(1); nt = 1400; %No. of time step C = 0.5; %Courant Number %% NON CONSERVATIVE FORM [Mass_flow_rate_NC, Pressure_NC, Mach_number_NC, rho_NC, v_NC, T_NC, rho_throat_NC, v_throat_NC, T_throat_NC,…

The 2D heat conduction equation is given by:   `(∂T)/(∂t)=α((∂^2 T)/(∂x^2 )+(∂^2 T)/(∂y^2 ))`                                    …

Questions: Create the mesh for bumper assembly, mesh size should be 6mm. Crush tube analysis Run the crash tube model as it is. (Case 1) Change the Inacti=6 and run. (Case 2) Create the type 11 contact and run. (Case 3) Remove both notches and remove boundary condition on rigid body node then run. (Case 4) Create a new…

Objective:Compare seven cases as discussed in the last three slides, in a tabulated format on the basis of:1. Total number of cycles, Energy error, mass error and simulation time.2. Notice the animation of all five and describe the animations in brief, on thebasis of whether the elements are being deleted or cracked.3.…

Questions: Comparison of results with base simulation and improved shell element properties 1. Using the crash beam file from the previous assignment, change the run time to 55 msec. 2. Change the number of animation steps during simulation to a minimum of 25 and maximum of 60. Run the base simulation without any modification…

Assignment 2:   Questions: 1. Check the material properties of the rail component and calculate the speed of sound in steel rail=_______ 2. The length of the rail is about 1000 mm. Calculate the time takes for a shock wave to travel from one end of the rail to the other. 3. Time for sound to travel length of…

Assignment1:  Objective: Clean the geometry. Extract midsurface. Clean midsurface geometry. Ignore holes less than dia 5mm. Create a 2D mesh with target length 5mm, min 3.5mm max 7mm. And assign proper thickness, by creating a generic property.     Solution 1. The model in consideration is depicted in the…
