Numerical study on periodic pressure fluctuations driven by air–water interactions in a dropshaft-tunnel system

Engineering Applications of Computational Fluid Mechanics
Air–water interactions in deep tunnel systems can cause safety risks. However, the multiphase flow dynamics under continuous air entrainment from upstream and release from downstream, which are the typical case in engineering practice, remain ...

Experimental and Numerical Investigation of Cedar Façade Flame Spread With Respect to Sidewall

Fire and Materials, EarlyView.
ABSTRACT In response to growing energy conservation and carbon neutrality efforts, façade systems incorporating wooden materials have attracted increasing attention, which in turn raises concerns about their combustibility. This study presents a combined experimental and numerical investigation of flame spread along cedar façades.

An Experimental Investigation on the Impact of Burner Height and Location on the Characteristics of Externally Venting Flames

Fire and Materials, EarlyView.
ABSTRACT Fire sources in actual compartment fires exhibit a predominantly uneven spatial distribution. In this context, the impact of the height and location of the fire source, as well as the heat release rate (HRR) of the fire, on the thermal characteristics of Externally Venting Flames (EVF) is experimentally investigated.

Rethinking ethanol separation in continuous spirit production from a process intensification perspective

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract Continuous neutral‐alcohol and food‐grade ethanol production is an energy‐intensive process in which distillation and rectification alone account for 50–85% of total plant energy use. While significant advances in separation technology have emerged over the past two decades, the spirits industry continues to rely predominantly on multi‐effect ...

Effect of AEA-SP Dosage Sequence on Air Entrainment in FA Concrete

Nordic Concrete Research, 2019
Laboratory measurements show that varying the dosage sequence of air-entraining agent and co-polymer in the mix (SP added before, after or together with AEA) greatly affects air entrainment in fresh and hardened fly ash concrete.

INVESTIGATION ON EFFECTS OF ENLARGED PIPE RUPTURE SIZE AND AIR PENETRATION TIMING IN REAL-SCALE EXPERIMENT OF SIPHON BREAKER

Nuclear Engineering and Technology, 2014
To ensure the safety of research reactors, the water level must be maintained above the required height. When a pipe ruptures, the siphon phenomenon causes continuous loss of coolant until the hydraulic head is removed.

Modeling Study on the Entrainment of Ambient Air into Subsonic Laminar and Turbulent Argon Plasma Jets

, 2007
Modeling study is performed to reveal the special features of the entrainment of ambient air into subsonic laminar and turbulent argon plasma jets. Two different types of jet flows are considered, i.e., the argon plasma jet is impinging normally upon a ...
