Periodic Reporting for period 1 - NoStaHo (Non-Stationary Non-Homogeneous Turbulence)
Okres sprawozdawczy: 2022-10-01 do 2025-03-31
A wide range of radical technological breakthroughs are needed across all industries and engineering
because of the dramatic current climatic, environmental and population growth constraints on energy,
energy efficiency, polution and emissions. Turbulent flows are a key limiting factor in a vast range of these
industries including the aeronautical, automotive, chemical, pharmaceutical and environmental engineering
industries to name but a few. Step-change technological innovations in these industries therefore require
rapid and reliable turbulent flow prediction methods which are currently unavailable. The stalemate in
turbulence prediction methods reflects an 80-year stalemate in our fundamental understanding of turbulent
flows. The past years, however, have seen a number of advances which overturn cornerstone turbulence
textbook material and create an unprecedented opportunity for a potentially decisive breakthrough in our
fundamental and general understanding of turbulent flows which are typically non-stationary and/or non-
homogeneous. These recent advances concern non-stationarity and non-homogeneity in fundamental ways
and open new research opportunities with many new questions and hypotheses. This project seizes
these new research opportunities with a combination of laboratory, computational and theoretical methods
and approaches applied to a variety of turbulent flows. The expected outcome is a transformative, entirely
new and extensive, fundamental understanding and theory of non-stationary and/or non-homogeneous
turbulence, and a consequent road map for future disruptive turbulent flow prediction meth
