Air standard Cycle using Python

Aim The aim of this program is to fit a linear and cubic polynomial for the given data between heat capacity and temperature. Program The linear polynomial and cubic polynomial are defined in 'func_1' and 'func_3'. The data file is read in a function called 'readfile' which returns the values of temp and heat capacity…

Aim The aim of this program is to parse data from given engine data file and use the data to plot graphs according to the users input. Formulae `n=(RPM)/(2*60)` `P=W*n` `SFC=(f*1000)/P` Program The user is asked to input the file name which contains the engine data. 'try except and finally' are used to open the file in…

Aim The aim of this program is to simulate a rankine cycle and plot its T-s diagram and h-s diagrams. It also calculates the efficiency and back work ratio of the cycle based on the users inputs. In this rankine cycle: 1-2 is isentropic compression in a pump2-3 is constant pressure heat addition in a boiler3-4 is isentropic…

Aim The aim of this program is to solve the ordinary differential equation(ODE) which governs the motion of a pendulum and to simulate its motion. Equation The ODE equation is `(d^2theta)/dt^2 + b/m*(d theta)/dt+g/L*sintheta=0`which is split into two first order differential equations `(d theta_1)/dt=theta_2`…

Aim The aim of this program is to plot a P-V diagram for an otto cylce with given state parameters and engine design parameters and to find the efficiency of this cycle. Formulae `(P*V)/T=CONSTANT` `P*V^(gamma)=CONSTANT` `V=V_c*(1+1/2*(r-1)*[R+1-costheta-(R^2-(sintheta)^2)^(1/2)])` `V_s=(pi)/4*(BORE)^2*stroke` `V_c=(V_s)/(r-1)`…

Aim The aim of this program is to simulate a dual cycle and calculate the cycle's thermal efficiency, net work done and the mean effective pressure. The variation of the efficiency against cycle parameters such as compression ratio, cutoff ratio and alpha value are plotted. Dual cycle 1-2 is isentropic compression 2-2.5…

Genetic Algorithm Genetic Algorithm (GA) is a search-based optimization technique based on the principles of Genetics and Natural Selection. They are commonly used to generate high-quality solutions for optimization problems and search problems. Genetic algorithms simulate the process of natural selection which means…

Aim The aim of this program is to fit a linear and cubic polynomial for the given data between heat capacity and temperature. Also this program sheds light on how to improve the cubic fit and the goodness of fit characteristics. Program The data is given and is used in the program through the "load" command. The temperature…

Aim The aim of this program is to parse the given data file which contains thermodynamic coefficients of various species and calculate their specific heat, enthalpy and entropy values over a temperature range.  Formulae used Equations used in this program are: `Cp=R*(a1+a2*T+a3*T^2+a4*T^3+a5*T^4)` `H=R∗T∗(a1+a2∗T/2+a3∗T^2/3+a4∗T^3/4+a5∗T^4/5+(a6)/T)`…

The aim of this program is to plot a P-V diagram for an otto cylce with given state parameter and engine design parameters and to find the efficiency of this cycle. The equations used in this program are: `(PV)/T=CONSTANT` `PV^(gamma)=CONSTANT` `V=Vc*(1+1/2*(cr-1)*[R+1-costheta-(R^2-(sintheta)^2)^(1/2)])` `Vs=(pi)/4*(BORE)^2*stroke`…
