Aims of the teaching

The purpose of this course is the acquirement of basic training in understanding the types and usefulness of different types of heat exchanger. Acquire a very solid and yet flexible (adaptation to different geometries or phenomenology) in the calculation of heat exchangers by the conventional methods, integrating the knowledge of calculation algorithms with the basics of heat transfer competition. Know the different levels of calculation of heat exchangers (porosity method, detailed calculation dimensional flows through ducts, solving the Navier-Stokes) and their combination. It aims to provide the tools and criteria to adapt the level of simulation/ analysis to the needs of the company or researcher/engineer involved.

The main contents are:

Introduction to heat exchangers

Theoretical basis for thermal and hydraulic designing

Heat exchangers without phase change: double-pipe, plates, shell and tuve

Heat exchangers with phase change: evaporators, condensers

Compact exchangers: fin-tube, regenerators

Micro heat exchangers.

Intended Learning outcomes (measured by the assessment)

At the end of the course, the student has to acquire knowledge on:

Consolidation of basic aspects of phenomena of heat and mass transfer (mathematical formulation, analytical techniques and numerical resolution, ...), as part of a technological application of large industrial and social importance are like heat exchangers

Consolidation of conventional methods of calculation of heat exchangers (F factor methods, e-NTU NTU P, etc.). Description of the main technical characteristics and peculiarities of calculation of heat exchangers different regarding geometry (double pipe, shell and tube, plates, compact fin-tube) and phenomenolog y (evaporators, condensers, heat by combustion).

Application of advanced methods of numerical simulation of heat exchangers dimensional fluid analysis, in case of steady state or transient flow and with or without phase change (condenser, evaporator).

Introduce the most advanced methods of calculation of heat exchangers where the fluid analysis is multidimensional, by methods with macro control volumes (porosity type methods) or more advanced methods based on detailed multidimensional solving Navier-Stokes equations.
