AbstractThis paper attempts to answer Lyman's question (1990) on the non-uniqueness in defining the 3D measure of the boundary vorticity-creation rate. Firstly, a straightforward analysis of the vorticity equation introduces a definition of a general vorticity flux-density tensor and its ‘effective’ part. The approach is strictly based on classical field theory and is independent of the constitutive structure of continuous medium. Secondly, the fundamental question posed by Lyman dealing with the ambiguity of the 3D measure of the boundary vorticity-creation rate for incompressible flow is discussed. It is shown that the original 3D measure (for an incompressible Newtonian fluid defined by Panton 1984), which is reminiscent of an analogy to Fourier's law, is in its character ‘effective’ and plays a crucial role in the prognostic vorticity transport equation. The alternative 3D measure proposed by Lyman includes, on the other hand, a ‘non-effective’ part, which plays a role in the local determination of the ‘effective’ measure as well as in a certain diagnostic integral boundary condition.

Local Determination

Following the experience with the Horizon-10T detector systems, a completely new detector of Extensive Air Showers (EAS) has been designed to be built at Nazarbayev University, Astana, Kazakhstan. The motivation of building HorizonT-Kazakhstan is to study in detail the phenomenon of the multi-modal EAS events that were initially explored by Horizon-8T and 10T detector systems. This detector will have a ns-level resolution of charged particle arrival times and pulse shape resolution. Each detection point is designed to have a total scintillation area approximately equal to 7.7 m2 and consists of three 1.6×1.6 m detectors located in a triangular arrangement for the local determination of the EAS disk arrival direction, and to have ns precision in timing between points. Local arrival direction is important following evidence of large angle differences in the multimodal events seen previously.
