PIV of swirling flow in a conical pipe with vibrating wall
, 2018 Swirling flows in conical pipe can be found in a number of industrial processes, such as hydrocylone, separator and rotating machinery. It has been found that wall oscillations can reduce the drag in water channel and pipe flows, but there is no study of

Fluid Flow through 90 Degree Bends [PDF]
, 2008 Pressure drop measurement and prediction in curved pipes and elbow bends is reviewed for both laminar and turbulent single-phase fluid flow. For curved pipe under laminar flow, the pressure loss can be predicted both theoretically and using empirical ...

, 2002 Magma viscosity is strongly temperature-dependent. When hot magma flows in a conduit, heat is lost through the walls and the temperature decreases along the flow causing a viscosity increase. For particular values of the controlling parameters the steady-

Thermo-fluid dynamics of pulsating heat pipes for LED lightings
Mechanical Engineering Journal, 2016 An effectual thermal management is a very important issue in a light emitting diode (LED) floodlight because its performance and reliability decrease significantly as the junction temperature increases.

PULSATING HEAT PIPE IN HYPERGRAVITY CONDITIONS
Heat Pipe Science and Technology, An International Journal, 2015 A closed-loop pulsating heat pipe made of a copper tube (1.1 mm/2 mm I.D./O.D.) and filled with FC-72 has been tested in a large-diameter centrifuge (LDC) of the European Space Agency in Noordwijk at different hypergravity levels up to 20 g, different heat input levels, and different orientations with respect to the gravity direction (vertical bottom ...

Pulsating Heat Pipes: Basics of Functioning and Modeling [PDF]
, 2018 For cooling of electronic or electric equipment, there is a growing industrial demand of high-performance thermal links. One such thermal device is the recently invented pulsating (called also oscillating) heat pipe (PHP). It consists of a closed capillary tube folded into meander and partially filled with a liquid.

Физические процессы теплообмена при миниатюризации испарительно-конденсационных систем термостабилизации [PDF]
, 2014 Розроблено нову комплексну математичну модель процесів теплообміну в умовах зменшення внутрішнього простору випарно-конденсаційних систем (мініатюрних теплових труб, термосифонів і пульсуючих капілярних теплових труб).

Advanced Functional Materials, EarlyView.This study demonstrates that pulsed potential electrolysis significantly improves CO2 reduction performance on copper‐nitrogen doped carbon electrodes. The formation of cationic copper sites and metallic clusters as a function of applied intermittent potential leads to notable selectivity changes compared to potentiostatic reduction.
