Objective
The objective of this project is to carry out a thermal and fluid-dynamic optim isation of fin-and-tube heat exchangers (for the refrigeration, air conditionin g and automobile industries) with the purpose of obtaining significant reductio ns in both size and weight (typically 20%). This objective is going to be done by means of the development of new high performance heat transfer surfaces and new optimised internal flow circuitry. Due to the large number of parameters in volved in the design of these heat exchangers, advanced computational and exper imental facilities will be specially adapted to carry out systematic studies co nducted to the development of new design conceptions. Significant energy saving s during the heat exchanger operational life (low pressure drop, innovative and optimised defrosting systems,) will also be obtained. Three different compu tational simulation levels, specially adapted for this project, will be employe d: i) advanced detailed fin-and-tube exchanger design code (FTDEcode) for the n umerical simulation of the thermal and fluid behaviour of the complete heat exc hanger; ii) specially adapted high-level general-purpose CFD codes to obtain lo cal properties of the flow through characteristics portions of the heat exchang er (e.g. the modelization is carried out on few tubes and fins) and/or particu lar physical phenomena (moist air condensation, frost deposition,). Differe nt experimental facilities will be specifically adapted or built to test the pr ototypes and to validate the numerical computations: i) experimental set-ups (wind tunnels and calorimeters) for the study of the whole heat exchanger using , whenever possible, full-scale heat exchangers models; ii) experimental set- ups to evaluated local properties of the flow in characteristic parts of the he at exchanger (e.g. experimentation on large-scale fin-and-tube geometries, or small loop detailed experiments for the analysis of the single and twophase flo w in internal ducts with or without fins). As a consequence of the systemati c computational and experimental studies mentioned above, different prototypes based on new design concepts and high performance heat transfer surfaces will b e constructed and tested to produce, after the end of this project and within a reasonable period of time (less than one and a half year), optimised commercia l fin-and-tube heat exchangers taking into account the specific activities of t he SME proposers (refrigeration, air-conditioning and automobile fields).
