An experimental investigation of flow boiling heat transfer characteristics and the triggering mechanisms of CHF in a natural circulation loop under moderate to low driving forces

Flow boiling heat transfer, flow instability, and critical heat flux (CHF) were investigated experimentally in a vertical R134a natural circulation loop with an integrated reservoir. Tests on flow heat transfer characteristics and flow visualization were conducted at filling rati...

Effects of Upstream Porous Treatments on the Hydrodynamic and Hydroacoustic Performances of a Hydrofoil

This paper presents numerical studies on the effects of upstream porous treatments on the hydrodynamic and hydroacoustic performances of a hydrofoil. The inflow velocity is 5 m/s and the chord-based Reynolds number is 2.5 × 107. A rapid turbulent boundary layer (TBL) noise predic...

The ‘step stall’ phenomenon of a supersonic Coanda jet

This study presents an experimental investigation into the influence of a step on the detachment characteristics of a supersonic Coanda jet. A parametric analysis was conducted by systematically varying the Coanda surface radius, jet outlet height and step height. Flow morphology...

Multiscale sensitivity analysis of elasticity properties for woven composites using data-driven self-consistent clustering analysis and artificial neural network

<title>Abstract</title> Sensitivity analysis of material microscopic properties like matrix and fiber parameters on macroscopic performance is critical for the refined design of the mechanical properties of woven composites. However, this work remains challenging due to the high...
