Experimental study of the interaction between thermal plumes and human breathing in an undisturbed indoor environment
(Peer reviewed; Journal article, 2020)This study characterized the interaction between human thermal plume and breathing air flow while people are sitting in a quiescent indoor environment. A sitting breathing thermal manikin was developed to mimic a real ... -
Experimental study of the mutual interactions between waves and tailored turbulence
(Peer reviewed; Journal article, 2023)When surface waves interact with ambient turbulence, the two affect each other mutually. Turbulent eddies get redirected, intensified and periodically stretched and compressed, while the waves suffer directional scattering. ... -
Experimental study of the simultaneous effect of nano-silica and nano-carbon black on permeability and mechanical properties of the concrete
(Journal article; Peer reviewed, 2019)The permeability level and resistance of the concrete cutoff wall of earth dam on the penetration of fluids are crucial factors and have an essential effect on the stability of the concrete core. In this research, the ... -
Experimental study of the use of tracing particles for interface tracking in primary cementing in an eccentric hele–shaw cell
(Peer reviewed; Journal article, 2021)We present the results of the displacement flows of different Newtonian and Herschel–Bulkley non-Newtonian fluids in a new-developed eccentric Hele–Shaw cell with dynamic similarly to real field wellbore annulus during ... -
Experimental Study of Thermal Buoyancy in the Cavity of Ventilated Roofs
(Journal article; Peer reviewed, 2020)Pitched wooden roofs are ventilated through an air cavity beneath the roofing in order to remove heat and moisture from the roof construction. The ventilation is driven by wind pressure and thermal buoyancy. This paper ... -
Experimental Study of Thermal Conductivity and Compression Measurements of the GDL-MPL Interfacial Composite Region
(Journal article, 2016)MPL and GDL in a PEM fuel cell assembly are often treated as separate layers in the literature. However, there exists a considerable interfacial region where the two different materials merge. The MPL consists of fine ... -
Experimental study of vortex-induced vibration of a twin-tube submerged floating tunnel segment model
(Peer reviewed; Journal article, 2020)The cross-flow vortex-induced vibration features of a submerged floating tunnel element, which is composed of two rigidly connected cylinders in a tandem configuration, were investigated via a self-oscillation model test ... -
Experimental Study on Charcoal Production from Woody Biomass
(Journal article; Peer reviewed, 2016)In the present work, effects of process conditions on char and fixed carbon yields from four woody biomasses were studied. The influence of the particle size, sample mass, and pressure on experimental values of char and ... -
Experimental study on fast-switching series-connected SiC MOSFETs
(Chapter, 2017)This paper presents an experimental study on series-connection of Silicon Carbide MOSFETs. The switching performance of two series-connected SiC MOSFETs rated at 1200 V and having on-state resistances of 80 mΩ was tested ... -
Experimental study on phase change solvents in CO2 capture by NMR spectroscopy
(Journal article; Peer reviewed, 2013)2-(Diethylamino)ethanol (DEEA) and 3-(Methylamino) propylamine (MAPA) in combination may represent a promising absorbent system for CO2 capture due to high CO2 loading capacity, high equilibrium temperature sensitivity, ... -
Experimental study on power curtailment of three in-line turbines
(Journal article; Peer reviewed, 2017)A dataset of wind tunnel power and wake flow measurements on a setup of three aligned model wind turbines is presented. The power outputs of the three turbines are in good agreement with measurements from a full-scale wind ... -
An experimental study on pre-stretched double-chamber 6000-series aluminium profiles subjected to quasi-static and dynamic axial crushing
(Peer reviewed; Journal article, 2020)Automotive crash boxes require a material selection with strength and ductility in a balanced combination. In this work, the behaviour of double-chamber AA6063 and AA6082 aluminium profiles subjected to quasi-static and ... -
Experimental study on the characteristics of pressure drop oscillations and their interaction with short-period oscillation in a horizontal tube
(Journal article; Peer reviewed, 2018)Long-period oscillations (pressure drop oscillations) and short-period oscillations (superimposed density wave oscillations) have been observed in many studies. However, under which condition the long-period oscillations ... -
