Heat Transfer and Fluid Mechanics 2Laajuus (3 ECTS)

Objective

On completion of the course the student will be able to solve basic cases of pipe, planar and space heat exchange in a stationary situation. He or she will be able to calculate the capacity of heat exchangers, to size the heat exchange surface, and to calculate the pressure loss of an exchanger in a simple case. The student is able to make use of information technology when calculating heat transfer.

Content

Forms of heat transfer. Energy balance in heat transfer. Pipe heat exchange and planar heat exchange. Temperature distribution in multilayer construction, heat exchange resistors and coefficient of heat passage. Parameters and their coverage in heat transfer technology and fluid mechanics. Correlation equations in convective heat exchange and Reynold’s analogy. Heat exchangers, logarithmic temperature difference and conductance. Radiation heat transfer and visibility coefficients.

Assessment criteria, satisfactory (1)

The tasks in the first part of the test consist of concept defining, recognition tasks, evaluation of statements and brief calculations.
The student is able to verbally explain concepts of heat transfer technology and recognizes heat transfer cases. He or she is able to choose the correct formula of a given set of formulas, remembers the meaning and correct usage of symbols, and is able to apply formula correctly according to given initial data in familiar cases. The student completes the first part of the test with a passing score.
The student is on the required level, has solved and returned one third of the course assignments by the deadline, and has completed the practical assignment. Some of the learning assignments require the use of information technology.

Assessment criteria, good (3)

In addition to the requirements above, the student is able to make use of the course material and his or her own material in the tasks of the second part of the test. The tasks in the second part of the test are extensive calculations.
The student is able to separate the essential from the given initial data, ignore the unessential, and to find or independently evaluate the missing initial data needed for the solution. The student is able to deduce and implement the correct process in multiphase tasks (e.g. sizing equipment, calculating heat exchange capacity and determining the final state of a fluid) which require multiple initial phases and combining them. The student completes both parts of the test with a passing total score.

Assessment criteria, excellent (5)

In addition to the requirements above, the student is able to solve the most demanding tasks of the first part of the test, which require assessment and reasoning. Further, the student is able to solve the most demanding tasks of the second part of the test, which require a new approach, almost without errors so that he or she completes both parts of the test with a passing total score.
In borderline cases the course grade will be raised by one from the exam grade, if the student has satisfactorily solved and returned two thirds of the course assignments by the deadline.
