1. The document describes models developed using Catia dymola behavior modeling software to simulate one-dimensional steady state heat conduction and heat conduction through cylinders. 2. The one-dimensional heat transfer model calculates the heat transfer rate through a wall of a selected material. The radial heat transfer model calculates the temperature at different points in pipes. 3. The models were tested by inputting initial temperature values and material properties. The results obtained from the simulations matched analytical solutions, validating that the models can accurately calculate linear and radial heat transfer rates.

Usingthedevelopedmodel, one can estimate the amount of heat conducted through different selected materials linearly as well as radially. Key Words: One-dimensional steady state Heat conduction, 3dexperiance. 1.INTRODUCTION Heat transfer basically deals with the transfer of heat from one surface to another. In the model heat gets transferred in 1D through wall, this wall can be of any selected material according to our preference. Thus, the linear heat transfer rate (Q) through the material is calculated. Similarly, the second code deals with radial heat transfer through pipes, thus we get the values of temperature at different stages. 1.1 Software used Catia dymola behavior software, This softwaredealswiththe modeling, design, and analysis of different models through blocks or through code for simulation. This is a powerful modelingand simulator which givers approximate/accurate solution. This software can do engineering-based processes for automobile, robotics, aerospace, which will help specifically Mechanical and Civil engineering students to visualize and see the results of their model. 1.2 Steps to create a model 1.2.1 Open dymola behavior modelling app Fig-1: Overview of 3dplm Start Dymola a Dymola window appears.
