# APPLIED THERMO-FLUID DYNAMICS Mod.1

## Learning outcomes of the course unit

Knowledge and ability to understand: At the end of the trail

teaching the student should know the basics

of the computational thermo-fluid dynamics.

Skills:

The student will gain knowledge of applicative relatively

to the theme of the numerical analysis applied to heat transfer and, more generally, to

transport phenomena of energy mass and momentum involved in engineering processes.

Making judgments:

The student will have the tools to deal choices

design in the field of numerical modeling of the heat transfer devices.

Communication skills: The student will have the ability to present clearly the

procedure adopted in the numerical modeling of heat transfer devices.

## Prerequisites

To follow the course with profit requires knowledge of the basic concepts

of Thermo Fluid Dynamics.

## Course contents summary

The course is structured into two parts: theory and practical lessons. The

theory lectures cover the following subjects: Equations of convection. Finite volume nanalysis. Finite element analysis. Turbulence and its models. The commercial codes for Computational Thermal Fluid Dynamics.

The exercise activity is an integral part of the course and is dedicated to

numerical exercises intended as a moment of verification and clarification

the theoretical knowledge acquired in the lectures. Part of the activities

Exercise is carried out in the computer lab and is dedicated

numerical analysis applied to

problems of heat exchange and fluid flow. In order to acquire

methodological knowledge and application, this part of the course makes use

practical exercises that use the programming Matlab, Comsol Multyiphysics and Ansys environment.

## Course contents

Convection Equations: Mass Conservation, Energy Conservation, Momentum Conservation. Methods of numerical solution. Solutions in primitive variables. Algorithms for incompressible fluids. Turbulent convection. Finite volume analysis: the basic idea. Discretization. Time integration. Methods of solving systems of linear equations. Thermofluidodynamic problems solutions: finite volume approach.

Finite element analysis. The basic concepts. Method of weighted residuals. Equations for the unsteady regime. Shape functions. Mapping elements. Numerical integration. Thermofluidodynamic problems solutions.

## Teaching methods

The theoretical part of the course will be illustrated by means of lectures.

Part of the practical activity is carried out in the computer lab and it also

includes an activity pursued independently by the students, followed by

an elaboration and discussion of the results.

## Assessment methods and criteria

The exam is based on a written/practical test, performed in the computer

lab, followed by an oral examination. The verification is so weighted: 50%

written test (correct resolution of a practical exercise), 50% oral exam

(correct and cmplete ansie to theoretical questions and speaking ability).
