Part 1 of the paper introduces the idea of SFT, i.e. solid-fluid-thermal analysis, and argues that it is what is needed to enable fluid-structure interactions to be handled, and especially those which arise in heat-transfer equipment.
Since finite-element techniques are commonly used for structural analysis and finite-volume ones for fluid flow, the question is raised: which is the more suitable for SFT? After an historical review of how the divergence between the FE and FV specialists arose, it is argued that the advantage for SFT lies on the FV side, as experience has demonstrated.
Part 2 of the paper discusses why it is that, except for nuclear boilers and steam condensers, heat-exchanger design is currently based on pre-CFD techniques, in which flow patterns are presumed rather than calculated.
One reason suggested is that data-input techniques for the relevant computer programs are not 'relational', and that this makes the method of parameterized design-optimization studies burdensome to perform. How to create a 'relational' data-input technique is indicated.
