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
