      Hi Sir,

      Is turbulence flow is possible in inviscid flow if, yes then how we can capture it? TIA


      Thank you,

      No: the main source of production of Turb is missing so flow might not necessary get turbulent and can stay laminar. Example: Potential Flow.
      Inviscid turbulence is "theoretical" more than "practical": You know the turbulence spectrum and Energy Cascade: it will spread to inifinite wave numbers because there is no molecular dissipation.

      Thank you very much, sir
      One follow-up question I know this might be a silly question but I want to know what is missing in the inviscid flow to produce turbulent flow? TIA

      The terms with the viscous terms are missing: Euler Euqations
