OVERVIEW

NUMERICAL HEAT TRANSFER AND FLUD FLOW

The course Computational thermal-fluid-dynamics is designed to develop students’ skills in solving simple applied thermofluidodynamics problems, in the presence of heat transfer, using commercial CFD codes.

AIMS AND CONTENT

LEARNING OUTCOMES

The students should achieve the skills of numerically solving partial differential equations for fluid flow

AIMS AND LEARNING OUTCOMES

To proceed to the numerical solution of the differential equations proper to the thermo-fluid dynamics, the student must develop the ability to perform, in a correct way, the engineering simplifications necessary to solve a simple case study.
The topics presented during the lessons and the activity, carried out autonomously, bring to the student the ability to analyze a concrete thermofluidodynamic problem. At the end of the course, students are able to adequately define the computational domain, the physical properties of fluids and materials, and the boundary conditions, in order to correctly set up the solution procedure, with a commercial CFD (Computational Fluid Dynamics) code.
This is focused to develop the ability to solve, correctly, small simple problems of thermo-fluid dynamics, using CFD.

TEACHING METHODS

The course consists of 36 h front –lessons and 24 h lab. In Italian.

SYLLABUS/CONTENT

EXAM DESCRIPTION

The oral examination is focused on the presentation and the discussion of a CFD analysis

ASSESSMENT METHODS

The oral examination is based on the discussion of the content of the report of the student’s CFD analysis (in paper or .pdf format, mandatory).

During the discussion, the student must:

• Describe the case study,
• Describe and justify the hypotheses that led to the definition of the CFD analysis model,
• Describe the choice of the form of Navier Stokes equations, used for the solution,
• Describe the correspondence between the real conditions and the boundary conditions used for the numerical resolution,
• Describe and comment on the results, using, if necessary, the use of results available in literature for similar cases.

The Commission assesses the adequacy of the student's exposure and its ability to respond to any objections and requests for clarification.
