Course Curriculum CFU Length(h)
[70/77]  CHEMICAL ENGINEERING [77/00 - Ord. 2014]  PERCORSO COMUNE 9 90

Objectives

The Course supplies the necessary competencies for the understanding of the fundamental principles of Fluid Mechanics and the ability to understand the phenomenology of laminar and turbulent flows.
The main aims of the course are:
• to stimulate the deepening of the knowledge about Fluid Mechanics peculiar of the industrial applications of Chemical Engineering;
• to induce the knowledge and the proper interpretation of the main phenomena of Fluid Mechanics involved in Chemical Engineering;
• to supply the students with a methodology of interpretation and computation concerning the balance of mass, momentum, forces and energy of fluids in the field of Chemical Engineering.
The expected learning results are:
• the ability to apply the acquired skills in the design and implementation of modelling and analysis of processes, in the field of hydrostatics and pipe flows;
• the ability to identify and use data to formulate responses to well-defined concrete and abstract problems;
• the ability to communicate about the above described phenomena with the peers, supervisors and clients of studies and simulations, and with people who develop and make use of simulation models;
• the learning skills to undertake further studies with some autonomy on particular phenomenological aspects;
• the ability to work in a group.

Prerequisites

Mathematics 1; Mathematics 2; Physics 1;

Contents

• Principles and equations of compressible Fluid Mechanics [15h frontal lect.]
• Hydrostatics [6h frontal lect. + 8h Exerc.]
• Laminar Boundary Layer and Prandtl equation [2h frontal lect.]
• Potential flows [6h frontal lect. + 2h Exerc.]
• Boundary Layer separation [2h frontal lect.]
• Turbulence [3h frontal lect.]
• Reynolds Equations [2h frontal lect.]
• Turbulence closures [2h frontal lect.]
• Turbulent Boundary Layer [2h frontal lect.]
• Flow equations [8h frontal lect.]
• Major and minor head losses [6h frontal lect. + 10h Exerc.]
• Pipe flows [6h frontal lect. + 10h Exerc.]

Teaching Methods

The lectures are arranged in order to stimulate the active participation of the students to the achievement of the conclusions, also through the recall of what have been already studied in past courses or in the present course. Moreover, exercises in the lecture room and in the laboratory are carried out during the course. In particular, during the exercises in the lecture room the students are divided in small groups; exercises concern the theoretical and numerical resolution of practical problems of Fluid Mechanics concerning Chemical Engineering. Laboratory exercises are conducted in a similar way. The reports are evaluated and at the end of the course and they contribute the conclusive mark for two points over thirty at most.
In particular, the hours of the course are divided in this way:
• frontal lectures: 50 h;
• seminars: 10 h;
• numerical exercises in the lecture room 25 h;
• experimental exercises in the laboratory 5 h.

Verification of learning

The conclusive test is an oral test with three queries, one or two about design/check, one or two about theory. The aim of the test is the evaluation of the acquired knowledge, particularly regarding the understanding of the engineering applications of the knowledge, and of the ability to apply it to an “open” practical case, that is a case where non every variable is fixed and the decisional choices are taken by the student (who has to demonstrate the ability to discuss and motivate them). The reports of the exercitations carried out during the classes are evaluated as well; they contribute the conclusive mark for two points over thirty at most.
