Title: Innovations of Frank Haselbach: A Look at His Patents and Career
Introduction
Frank Haselbach, an inventive mind based in Melbourne, GB, has made noteworthy contributions to the field of gas turbine technology. With a total of three patents to his name, Haselbach’s work accentuates innovative cooling methods that enhance the efficiency and performance of gas turbines.
Latest Patents
Among his latest patents is a groundbreaking method for impingement air cooling for gas turbines. This inventive approach involves applying cooling air velocity packs of specific amplitude and frequency to impingement air openings. This results in the formation of intervallic annular swirl structures that effectively penetrate a cross-flow and cool the gas turbine components with high intensity. The optimal cooling efficiency is achieved when the Strouhal number, determined by the ratio of amplitude and frequency to the size of cooling openings, ranges between 0.2 and 2.0, preferably between 0.8 and 1.2.
Another significant patent is the method and apparatus for cooling the outer shrouds of rotor blades in a gas turbine. This patent details a passive shroud cooling technique that utilizes a multitude of cooling air flows introduced into the hot-gas flow upstream of the rotor blades. These cooling-air streams are designed to hit the thermally loaded bottom surfaces of the outer shrouds, ensuring effective cooling.
