Elementos de Fluidos e Calor

Basic knowledge in Physics.

The curricular unit is organized into theoretical classes. Classes are dedicated to the exposition and discussion of the subjects taught. They are complemented with commented resolution of theoretical-practical applications.

The aim of this course is to give students basic concepts and scientific basis of thermodynamics, fluid mechanics and heat transfer. The student should be able to: Understand the basic laws of thermodynamics, particularly at the level of fluid behaviour and theoretical thermodynamic cycles and their applications; Understand and be able to apply the laws of fluid mechanics to incompressible fluids in pipes; Understand the various mechanisms of heat transfer; Select pipes thermal insulation; Identify and solve problems involving heat transfer.

Module 1 – Thermodynamics – Fundamental concepts. Properties of pure substances. Application of the first law of Thermodynamics to open systems and closed systems. Introduction to the Second Law of Thermodynamics. Thermodynamic cycles.

Module 2 – Fluid Mechanics  – Fluid properties. Static of fluids. Flow characteristics. Laminar flow in pipes. Turbulent flow in pipes.

Module 3 – Heat Transfer – Modes of heat transfer. Heat transfer equations. Steady state one-dimensional conduction: Flat walls; Cylindrical systems. Selection of pipes thermal insulation. Heat exchangers fins. Heat exchangers. Temperature and heat flux sensors.

Assessment:

            Module 1 - 33.33%          Module 2 - 33.33%          Module 3 - 33.33%

Students will be able to pass this Curricular Unit (CU) through assessment tests, carried out whenever possible, and final exams;

 Assessment tests: are valid – only – for the current academic year;

- Assessment tests will be carried out during classess, on dates defined by the teacher, at the end of each module;
- If, in a given assessment test (20 values), the student obtains a classification equal to or greater than 9.5 values, he is automatically exempted from taking that component in the final exam tests of the current academic year;
- If, in a given assessment test (20 values), the student obtains a minimum grade of 7.5 values, this grade is guaranteed in the exam periods (normal, resource and special), thus contributing to the overall average which, for final approval, must be equal or greater than 9.5 values.

Final Exams: assessment periods defined by the school (normal, resource and special).
