## Learning outcomes

The student learns how to solve numerically basic heat and mass transfer problems. In particular, the student learns how to: - solve stationary thermal conduction problems - solve transient thermal conduction problems - solve convective heat transfer problems in ducts

## Course contents

Students will acquire a basic knowledge the balance equations governing heat and mass transfer and of the main numerical methods employed to solve the balance equations. The procedure to obtain dimensionless balance equations will be presented. An introduction to the main numerical methods employed for solving heat and mass transfer problems will be presented.

Student will solve numerically, by using personal computers of the computer laboratory, the following type of problems: stationary/transient conduction; forced convection in ducts and thermal entrance regions; forced and natural convection in fluid saturated porous media; flows around obstacles; convection of non-Newtonian fluids.

The dimensionless balance equations will be solved by employing MATLAB (© MathWorks) first by means of the graphical interface PdeTool and then by writing a simple code.

MATLAB licences are free for the students of Università di Bologna.

## Readings/Bibliography

Lecture notes and virtual blackboard notes.

Arpaci V.S. Larsen P.S. CONVECTION HEAT TRANSFER PRENTICE-HALL INC. ENGLEWOOD CLIFFS 1984.

## Teaching methods

The students are invited, but it is not mandatory, to bring their own device (BYOD - Bring Your Own Device) since the lecture hall does not provide the students with personal computers. The lecture hall provides power sockets for the students devices.

## Assessment methods

The exam consists of solving numerically a basic heat and mass transfer problem, similar to those presented during the classes.

The student will pass the exam if he/she proves to be able of:
- obtaining the dimensionless form of the local balance equation, of the auxiliary conditions, and of the geometry relative to the presented problem
- solving numerically the problem in its dimensionless form

As function of the pandemic situation, the student will carry out the exam online by employing the platform EOL or in classroom.

If and only if the student does not want to record the mark, they have to send an email to michele.celli3@unibo.it containing the explicit request for refusing the mark obtained. Otherwise, the mark will be recorded four day after the communication of the mark.
