Unsteady Motion of Shock Wave for a Supersonic Compression Ramp Flow Based on Large Eddy Simulation

Frontiers in Energy Research, 2022
A large eddy simulation (LES) is conducted to investigate shock wave/turbulent boundary layer interaction in a 24° compression ramp at a high inlet Mach number of Ma=2.9.

Shock‐Assisted Flow Control System in Convergent‐Divergent Nozzle: A Numerical Study on Unconventional Protuberance With Different Geometry

Engineering Reports, Volume 8, Issue 5, May 2026.
A numerical investigation using 3D RANS simulations demonstrates significant effects of protuberance geometry—cubic, cylindrical, spherical, and conical—on shock‐induced thrust vectoring in supersonic nozzles. Cubic protuberances provide the maximum jet deflection (˜2°) with negligible thrust reduction.

Visualization Characteristics of a Sharp Focusing Schlieren Method.

Journal of the Visualization Society of Japan, 2000
A sharp focusing schlieren system gives a means for observing any cross section of a flow field, which is perpendicular to the test beam axis of the optical system. This is impossible for a conventional schlieren system. In this study, a sharp focusing schlieren system was designed with referring to the Weinsten's system to investigate visualization ...

Shape‐Changing Multiphase Microparticles from Complex Liquid Crystal Emulsions

Advanced Functional Materials, Volume 36, Issue 35, 30 April 2026.
Liquid crystalline network (LCN) microparticles are prepared from single, double (Janus), and triple emulsions through a simple and scalable bulk‐emulsification strategy. Under heating, the particles exhibit robust, reversible, large‐amplitude deformations that depend both on the morphology and the liquid crystals director field configuration.

Hepatic‐Differentiated Subpopulation in Clear Cell Renal Cell Carcinoma: A Multi‐Omics Analysis of Tumors With Lymphovascular Invasion

Cancer Medicine, Volume 15, Issue 4, April 2026.
A hepatic‐differentiated subpopulation is associated with lymphovascular invasion in clear cell renal cell carcinoma. A visual summary of the key findings from our multi‐omics analysis. The TITANIA framework enabled the identification of a hepatic‐differentiated ccRCC subpopulation characterized by the upregulation of liver‐like metabolic pathways and ...

Viscous effects on the position of cavitation separation from smooth bodies [PDF]

, 1975
Flow visualization by the schlieren technique in the neighbourhood of a fully developed cavity on two axisymmetric headforms has shown the existence of laminar boundary-layer separation upstream of cavitation separation, and the distance between the two ...
