Abstract:
1. A method for determining a rate of turbulent kinetic energy dissipation (TKED) in a turbulent fluid environment, the method comprising: providing a light source a first end of a predetermined path-length (L), for passing at least one beam of light through the turbulent fluid environment; using an angle of arrival detection unit for detecting an angle of arrival of the at least one beam of light wherein the angle of arrival detection unit includes a single lenslet; and by using at least one processor: obtaining an autocorrelation of an angle of arrival of light φ wherein θ is an angle of arrival of the light, VSF(θ) is a volume scattering function obtained as a function of a time series of a scattering angle of light and g calculating a temperature spectra E wherein Φ(k
