Development, production and testing of optimized designs of compact heat exchangers containing heat transfer surfaces with implanted vortex generators


Objectives of the project

The objective of the project is to develop a data base and a computer code to optimize the use of Vortex Enhanced Heat Exchangers (VEHE) in industry. Reliable methods for performance, prediction, design and production of Plate-Fin or Tube-Fin heat exchangers with implanted vortex generators will be elaborated. Methods for achieving a maximum reduction of weight and pressure drop will be given.

Technical approach

A feasibility study involving theoretical and experimental research work in cooperation with industry and research institutes will provide data and a methodology for performance prediction and optimization as well as practical methods for design and manufacture of vortex enhanced heat exchangers. The effects of geometric parameters on heat transfer will be investigated using different vortex generator shapes installed in different arrangements on the heat transfer surfaces. Computational modeling of heat transfer and fluid dynamics will be used for geometry optimization.
The results of the numerical studies will be experimentally verified by tests in wind tunnels on one-channel modules as well as on whole heat exchangers containing several vortex generators. A new measurement technology will be developed to identify the increase of the heat transfer caused by vortex generators.
A computer software for industrial prediction and design of VEHEs will be provided. Industrial partners will develop construction and cost-effective production methods.

Expected achievements and exploitation

Results are intended to be used initially by the consortium partners. The energy and material savings as well as the environmental benefits associated with this innovation will be published. The contributing universities and research organizations will exploit the results through the usual academic channels of presentations and publications. Seminars and workshops for potential industries will also be organized.
The developed software will be licensed to end users. Commercially significant innovations will be patented. The exploitation of the results will also be realized by bilateral agreements between the partners and third parties.
