A chamber, e.g. in a heat exchanger or flowing electrolytic half-cell, for through flow of a fluid which is capable of elastic turbulence has an internal structure with obstructions to compel flow to undergo successive changes of direction thereby applying stress to the flow of fluid through the chamber. The internal structure comprises an upstream portion in which the applied stress induces elastic turbulence to begin and a downstream portion which applies less stress per unit length and sustains the elastic turbulence while providing economy of pressure to propel the fluid. Configuration of the upstream portion may be planned with computer modeling so as to avoid formation of stagnant zones.
