Development and Application of Open Rotor Discrete Noise Prediction Program Using Time-Domain Methods

Applied Sciences
The aerodynamic noise of an open rotor is one of the critical challenges that must be considered in its design and application. FODNOPP, a program specifically programmed to predict the aerodynamic discrete noise of single- and counter-rotating open ...

Calpain small subunit homodimerization is robust and calcium‐independent

FEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Analysis of the Transonic Buffet Characteristics of Stationary and Pitching OAT15A Airfoil

Applied Sciences
Transonic buffet flow is a classical complex and unstable flow that has a negative effect on aircraft fly safety. Therefore, it is crucial to study the unsteady characteristics of buffet flow. The numerical analysis method is very useful in achieving the

Noise Reduction of Open Cavities by Passive Flow Control Methods at Transonic Speeds using OpenFOAM

Havacılık ve Uzay Teknolojileri Dergisi, 2021
Flow over a cavity is one of the most intriguing problems in aeronautics. Although geometry is simple, the physics of cavity requires uttermost attention.

Effect of Humidity on Transonic Flow [PDF]

Journal of Aircraft, 2008
An experimental investigation of the effects of humidity-induced condensation on shock/boundary-layer\ud interaction has been conducted in a transonic wind-tunnel test. The test geometry considered was a wall-mounted\ud bump model inserted in the test section of the wind tunnel.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Study on Rain Absorption Performance and Flow Field of Transonic Compressor under Different Working Conditions

Aerospace
Taking a four-stage transonic compressor as the research object, the Lagrange particle tracking method was used to simulate the multiphase flow by considering the particle fragmentation, collision and evaporation models, and the influence of different ...

Advection-dominated accretion flows with causal viscosity [PDF]

, 2006
We present the basic equations and sample solutions for the steady-state global transonic solutions of the advection-dominated accretion flows (ADAFs) with a causal viscosity prescription.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.
