B027547 - COMPUTATIONAL FLUID DYNAMICS FOR INDUSTRIAL APPLICATIONS

Italian

The course aims at providing the fundamentals of the modern CFD techniques with particular emphasis on industrial applications.

For Corso di Laurea in Ingegneria Meccanica:

CC2: In-depth knowledge and understanding of the theoretical-scientific aspects of mathematics and other basic sciences. To be able to use this knowledge to interpret and describe complex and/or interdisciplinary engineering problems.
CC3: Knowledge, understanding and use of scientific (computer and other) tools specific to the field of mechanical engineering design.

CA3: Applying knowledge and understanding related to the choice and application of appropriate analytical and modelling methods, based on mathematical and numerical analysis, in order to better simulate the behavior of components and plants in order to predict and improve their performance.
CA8: Applying knowledge and understanding related to the appropriate interpretation of the results of experimental tests, verification calculations and complex theoretical simulation processes, through the use of the computer, applying the acquired experimental, modeling, mathematical and informatics bases.
CA9: Applying knowledge and understanding related to the critically assessment of data and results, drawing appropriate conclusions, aware of the degree of uncertainty that may affect them.
CA12: Applying adequate knowledge and understanding to understand English texts.
CA15: Applying knowledge and understanding to achieve adequate preparation for tertiary level university studies (frequency to post-master's degree courses and doctoral schools) in order to further deepen knowledge and skills in research.
CT2: Cooperation in a work group
CT3: Development of technical discussions with appropriate arguments
CT4: Communication in graphical form (drafting of diagrams, graphs and tables)
CT6: Conduction of bibliographic research using the main resource (libraries, scientific databases, etc. etc.)
CT7: To respect commitments and deadlines
CT8: Communication using presentations and web systems.

For Corso di Laurea in Ingegneria Energetica:

The assessment of the student requires the completion of a written assignment. The document must be submitted and is assessed during the oral examination. The assignments are prepared working in a group of students (CT2: coordinated work group), must be submitted the day of the oral examination (CT7) in terms of written technical document in which the numerical and graphical results obtained are critically discussed (CT3, CT4).

The assignments consist of CFD analyses of test cases from the open literature (CT6). The student is asked to orally answer one or more questions aiming at assessing his/her ability to explain the course subjects.

The student must demonstrate to have acquired adequate knowledge of the numerical modeling methods of CFD (ENM-cc2, ENM-cc5) to set up appropriate analyses to obtain state-of-the-art fluid dynamics simulations, and obtain information to address design problems of industrial interest (ENM-ca2, ENM-ca4).
