Engine & Balsamico Design has developed to become a leader in the understanding of the use of efficient flow control mechanisms for defined vortex paths. At the start of our research the Ranque-Hilsch-Vortex-Tube (RHVT), a component of pneumatics for separating a gas flow into two partial flows, was the focus of our research. By hyperbolically tapering and expanding geometries, the flow resistance was significantly reduced and, in the process, a new ‘state of the art’ was defined. Turbulence is minimised by defined, predetermined spiral paths, thus ensuring optimum energy utilisation. For example, the use of a hyperbolic rolling vessel of rotation, in contrast to the cylindrical vessel of rotation currently used in the RHVT, already ensures a considerable increase in efficiency and particularly, separation efficiency. The optimised hyperbolic geometry eliminates dead space areas and supports the vortex in an energetically favourable pattern.

Results from the series of measurements led to a large number of energy and process engineering applications in which existing components were able to be improved to above average, and for completely new devices and processes to be developed. For example, in separation technology the novel vortex tube competes with membrane solutions. In the field of nozzle technology significant improvements have been achieved through the use of geometric adaptations. Work is continuing towards achieving an energetic optimum, as far as current production techniques will allow. In addition to developing its own products, Engine & Balsamico Design offers its knowledge of low-loss tube flows as an engineering design consultancy service to its customers.
