“…We begin with fluid mechanics, which defines turbulence as a form of gas or liquid flow with random transverse pulsations (Kochetkov et al 2019). Researchers in this field describe turbulence as irregular but not totally disorderly movements: "The swirling motion of fluids that occurs irregularly in space and time is called turbulence.…”

This Element aims to build, promote, and consolidate a new social science research agenda by defining and exploring the concepts of turbulence and robustness, and subsequently demonstrating the need for robust governance in turbulent times. Turbulence refers to the unpredictable dynamics that public governance is currently facing in the wake of the financial crisis, the refugee crisis, the COVID-19 pandemic, the inflation crisis etc. The heightened societal turbulence calls for robust governance aiming to maintain core functions, goals and values by means of flexibly adapting and proactively innovating the modus operandi of the public sector. This Element identifies a broad repertoire of robustness strategies that public governors may use and combine to respond robustly to turbulence. This title is also available as Open Access on Cambridge Core.

Annotation For the study of turbulent configurations in complex channels, it is proposed to use the experimental method of mass entrainment in combination with theoretical analysis and mathematical description of the results obtained. The paper presents the results of numerous experiments conducted on high-enthalpy gas flows in nozzles of complex shape. Images were obtained that visualize the picture of the torsion-wave dynamic movement of gas flows, the presence of stable structured turbulent flow configurations, and the abrupt transition from one form of flow stability to another.
