Flow over an airfoil

AIM: We have to write the script which should take column numbers as the input and plot the respective columns as separate images.The plot labels should be extracted from the file. If, someone request for a plot between column 1 (crank angle) and column 8(volume), then the label information should automatically be extracted…

1. What does popt and pcov mean? pcov- it is 2d array which estimated covariance of popt. The diagonals provide the variance of the parameter estimate. popt -  it is an array of Optimal values for the parameters so that the sum of the squared residuals of   is minimized. 2. What does np.array(temperature)…

we have to determining the minimum cushion pressure needed to break a given thickness of ice using an air cushion vehicle .      The equation is : First we import the math and matplotlib.pyplot library. we then define the function to represent mathematical model and pass two variable inputs. To simplify…

AIM OF THE PROJECT: Write a code on otto cycle and plot a PV diagram. and also calculate the thermal efficiency of the engine. THEORY: Air standard cycle: The four strokes of a 4 stroke engine are – 1. Suction/Intake Stroke :- In this stroke, the piston moves from TDC to BDC .The piston moves downward sucking the…

ABSTRACT: The way the pendulum moves depends on the Newtons second law. A second order Ordinary Differential Equation that describes the position of the \"ball\" w.r.t time.  Our objective is to write a program that solves the following ODE. This ODE represents the equation of motion of a simple pendulum with damping…

AIM: In this project ,we create  the 3d modelling of centrifugal pump and the basic simulation and then perform the parametric study. we also Obtain the relationship between Pressure ratio and mass flow rate and explain our results. CENTRIGUGAL PUMP:   “A centrifugal pump uses rotation to impart velocity…

AIM: In this project,we do CFD analysis the flow over NACA AIRFOIL with different angle of attack  ranging from 0to 10 degree with gap of 2 degree The link of used NACA AIRFOIL link:    Click Here to download the sample airfoil Data. Boundary condition and Inputs: units - SI unit analysis - external fluid…

AIM: Create a 3D model of a flow bench and run flow analysis and Obtain a plot of lift vs mass flow rate. We need to do the following Grid dependence test. Effect of valve lift on mass flow rate. DIMENSIONS: bore diameter=100mm length = 200mm   GRID DEPENDENCE TEST: we run the simulation at different at different…

AIM: In this project we Simulate the flow over a cylinder and then calculate the Reynolds number. Then increase the Reynolds number by a factor of 20%, 40%, and 100% then run the transient flow simulation.we Create animations for pressure-velocity for all the three Reynolds number. INTRODUCTION: 1.Reynolds number Reynolds…

stepwise explanation of code: First we  use clear all ,close all and clc to clear the workspace ,close the open tabs and clear the command the window respectively. we then define the length of arm1 and arm2 in l1 and l2 . we then define the angle between arm1 and horizonttal in thetha1 and  the angle between…
