Boundary-layer transition in the age of data: from a comprehensive dataset to fine-grained prediction
Wenhui Chang, Hongyuan Hu, Youcheng Xi +3
The laminar-to-turbulent transition remains a fundamental and enduring challenge in fluid mechanics. Its complexity arises from the intrinsic nonlinearity and extreme sensitivity t…
Direct numerical simulation of complete transition to turbulence with a fluid at supercritical pressure
Pietro Carlo Boldini, Benjamin Bugeat, Jurriaan W. R. Peeters +2
The objective of this work is to investigate the unexplored laminar-to-turbulent transition of a heated flat-plate boundary layer with a fluid at supercritical pressure. Two temper…
Sensitivity of three-dimensional boundary-layer stability to intrinsic uncertainties of fluid properties: a study on supercritical CO2
Jie Ren, Yongxiang Wu, Xuerui Mao +2
The intrinsic uncertainty of fluid properties, including the equation of state, viscosity, and thermal conductivity, on boundary layer stability has scarcely been addressed. When a…
Direct Numerical Simulations of K-type transition in a flat-plate boundary layer with supercritical fluids
Pietro Carlo Boldini, Benjamin Bugeat, Jurriaan W. R. Peeters +2
We investigate the controlled K-type breakdown of a flat-plate boundary-layer with highly non-ideal supercritical fluid at a reduced pressure of . Direct numeric…
