Objectives

This course provides the students with notions about experimental methods and measurement techniques, in the fields of Fluid Mechanics and Heat Transfer, to allow the students to choose between available methods and instruments. Data analysis and measurement uncertainties are also treated, in order to correctly represent experimental results, and to adequately plan the experiments. The aim of the lab component is to give students the training in experimental work, to consolidate theoretical concepts and to promote the capacity to do team work.

Program

EXPERIMENTATION IN ENGINEERING: general considerations. MEASUREMENT SYSTEMS: General topics (revision). ANALYSIS OF EXPERIMENTAL DATA: Errors and uncertainties; presentation of experimental results. PRESSURE MEASUREMENT: Manometers and electric pressure transducers. VELOCITY MEASUREMENT: Pitot tube, thermal and optical anemometers. FLOW RATE MEASUREMENT: Flow-obstruction methods and electric transducers for volumetric and mass flow rate measurements. THERMOMETRY: Thermocouples, resistance and radiation thermometers (revision); effect of heat transfer on temperature measurement; errors of system/sensor interaction. HYGROMETRY: electrical, psychometric and condensation methods. LABORATORY ASSIGNMENTS.

Teaching methods and learning activities

Lectures, tutorials and laboratory sessions. The students must do several lab experiences and write the corresponding reports for evaluation.

Software

EES - Engineering Equation Solver

Evaluation Type

Distributed evaluation with final exam

Eligibility for exams

General regulations and a mark of 10/20 in the set of the components of evaluation (A), (B) and (C).

Calculation formula of final grade

(A) Laboratory works and reports
(B) Performance in lab sessions
(C) Preparation of a formal written report
(D) Final exam

GRADE = 0.30 A + 0.15 B + 0.10 C + 0.45 D

The final grade (FG) results from the combination of the following components:
(A) Laboratory works and reports
(B) Performance in the laboratory sessions (includes mini-tests (B1) and form results (B2))
(C) Final exam (minimum 8 out of 20).

The FG = 0.40 A+ 0.15 B1 +0.1 B2 + 0.35 C

In the last class there will be a mutual assessment of performance by the elements of each group in order to assign to each element the grade of the reports component in consonance with his/her actual effort.

Examinations or Special Assignments

I) Students with frequency obtained in previous years: the student does not need to attend classes.
II) Students without frequency: evaluation is identical to that of the regular students.

Special assessment (TE, DA, ...)

The general rules of the Faculty will be followed.

Classification improvement

Students with frequency can do a resit exam or a classification improvement exam, covering all the contents with a weigh of 45% for the final classification.
