1. AIM:      To find thermal efficiency and plot PV diagram in Octave 5.2.0 2. GOVERNING EQUATIONS:      p*(v^gamma)=constant      pv/t=constant where p-pressure v-volume t-temperature gamma-specific heat ratio      Thermal Efficiency = 1-((t4-t1)/(t3-t2))=1-(1/cr)^(gamma-1)…

AIM To parse the NASA's THERMO.dat file to calculate required datas CODE EXPLANATION To find no of lines and no of species, seperate code is done  %parsing file clc clear all close all f1=fopen('THERMO.dat','r') c=0; noline=0; ct=0; while (c==0) line=fgetl(f1); if (line(length(line))=='1') ct=ct+1; end noline=noline+1;…

AIM To create a Rankine Cycle Simulator using OCTAVE CODE EXPLANATION Rankine cycle The thermodynamic cycle used in most of the turbines. It consists of Heat exchanger(HE) like boiler which heats the working fluid usually water, turbine where the steam expands, condenser where expanded steam condense, pump which circulates…

Aim Create 3D models for driver and driven wheels. Perform motion analysis by rotating the driver wheel at 10rpm. Obtain the following plots Contact force (between driving and the driven wheel) as a function of time. Angular Displacement of the driven wheel. Compare the contact forces with and without "Precise contact"…

Air Standard Otto Cycle Simulator Using Python  AIM: To solve an otto cycle to find thermal efficiency and make PV plot using python programming language.   PROBLEM STATEMENT: Otto cycle is a air standard cycle.  Though it is ideal cycle due to few assumptions made, still it is basis for current…

AIM: To compare the Diesel cycle and Otto cycle with same compression ratio, in terms of PV diagram, TS diagram, Efficiency using MATLAB.   INTRODUCTION:   The working fluid remains a gas throughout the entire cycle. It is called as ‘Air standard cycle’, because, the working fluid closely resembles…

PLANETARY GEAR MOTION ANALYSIS AIM: To create motion analysis for planetary gear system using solidworks MBD.   INTRODUCTION: Planetary gear system also know as epicyclic gear system has 3 main components, namely, sun gear (a normal spur/helical gear), a ring gear (internal teeth gear, aka annular gear) and no. Of…

Simple pendulum animation by Solving second order ODEs  AIM: To write a program in Python that will simulate the pendulum motion.        PROBLEM STATEMENT: A ordinary differential equation (ODE) is a differential equation containing one or more functions of one independent variable and…

AIM: To write python code to fit a linear and cubic polynomial for the Cp data.    INTRODUCTION: What is curve fitting? Creating a curve (by creating curve equation using mathematical functions) that closely resembles the curve plotted using original set of datas. Why do we need it? i) To get functional relationship…

Data analysis AIM:  To write a python script that tells parameters of engine and plot graph, find area under PV graph, power specific file consumption by reading the given file datas.   PROBLEM STATEMENT: From the given file engine_data.out we have to extract datas of various parameters Display the parameters…

AIM: To find out the critical frequencies of a rotating shaft Solidworks simulation.   INTRODUCTION: What is simulation? Simulation mimics the real process under certain condition in computer software using Finite Element Analysis FEA. FEA basically divides the object into number of small parts. This process is known…

MBD Simulation on a Piston Assembly AIM To study motion analysis for piston assembly using Solidworks motion.   INTRODUCTION Piston assembly, here, includes piston, gudgeon pin, connecting rod and crankshaft. This assembly works on principle of crank-slider mechanism, converting translational motion of piston to rotational…

IC ENGINE VALVE TRAIN MOTION ANALYSIS (MBD)   AIM To create MBD Simulation on IC Engine Valve Train and analyse the result.   INTRODUCTION Valve trains are an important part of a 4 stroke IC engine as it determines when the air/fuel charge should enter the combustion chamber as well as when the burnt gas goes…
