An Approach to Flow Engineering Via Functional Flow Modules

Book excerpt: Complex three dimensional flow fields are seen to consist of identifiable, morphologically invariant, mildly interacting, flow structures or modules. Outputs of such flow fields such as wind loads, heat and mass transfer, flow quality, mixing, and pressure losses can be rationally established and with a knowledge of the modular structure. The paper discusses the modular approach for the case of flows around three-dimensional obstacles in boundary layers and for the case of tailoring free-stream flow and turbulence by flow inserts such as screens, perforated plates, honeycombs and foam slabs.
