Abstract
The paper presents an improvement to the Turbulent Spot method for generation of synthetic turbulence. Earlier versions of the Turbulent Spot method and the Synthetic Eddy method were only able to produce turbulence which does not obey the continuity constraint in general. This was only possible for special cases (isotropic or near-isotropic turbulence).The proposed extension enables the generation of arbitrary anisotropic turbulence and fulfillment of the continuity constraint at the same time. This is made possible by the introduction of a new type of turbulent structure. The derivation of the internal velocity field is given. Also, expressions for the statistical properties of the new structure are derived.The performance of the proposed extension is illustrated on generic test cases.
