    Temperature profile through a Steel cylinder vs time

    Thank you for your questions, the cylinder is in vertical position (20m long) with an initial temperature of 240°C, imagine a shell and tube heat exchanger where the gas flow enters (initial temperature 250°C) through the top (shellside) flowing downward heating up the outside surface of...

    Temperature profile through a Steel cylinder vs time

    I am having trouble developing an algorithm to solve this problem required for a warming up procedure. I have a steel cylinder (hollow) which is being heated up with a gas from the outside and I wish to know the temperature distribution of the gas as it cools down and from the steel cylinder as...
