An experiment and simulation of smoke confinement utilizing an air curtain
TL;DR: In this article, the air curtain discharge velocity, the different efficacy of smoke confinement between hung wall and air curtain, as well as the dimension of air curtain outlets were discussed, and a suitable range of the breadth was proposed.
Journal ArticleDOI
Wind effects on air curtain performance at building entrances
TL;DR: In this article, the authors evaluated the performance of air curtains under different wind speeds and directions, and their interactions with air curtain jet considering different supply speeds, angles, and pressure differences across the air curtain.

An experiment and simulation of smoke confinement and exhaust efficiency utilizing a modified Opposite Double-Jet Air Curtain
TL;DR: In this paper, a study including an experiment and a numerical simulation was performed to determine the efficacy of a modified Opposite double-Jet Air Curtain (ODAC) is introduced in order to confine smoke movement and to exhaust smoke during a high-rise building fire.
Journal ArticleDOI
Comparison between Lagrangian and Eulerian approaches in predicting motion of micron-sized particles in laminar flows
TL;DR: In this article, an in-house particle tracking code was developed to simulate the motion of particles with Lagrangian approach, the solution to the transport equation with appropriate initial and boundary conditions was used.

Validation of steady RANS modelling of isothermal plane turbulent impinging jets at moderate Reynolds numbers
AA Adelya Khayrullina,Twan van Hooff,Twan van Hooff,Bert Blocken,Bert Blocken,Gert Jan van Heijst +5 more
TL;DR: In this article, the authors presented a validation study of steady Reynolds-averaged Navier-Stokes turbulence models for predicting isothermal plane turbulent impinging jets at two different slot Reynolds numbers, i.e. Re = 8,000 and Re = 13,000, based on 2D particle image velocimetry measurements.

The numerical computation of turbulent flows
Brian Launder,D. B. Spalding +1 more
TL;DR: In this paper, the authors present a review of the applicability and applicability of numerical predictions of turbulent flow, and advocate that computational economy, range of applicability, and physical realism are best served by turbulence models in which the magnitudes of two turbulence quantities, the turbulence kinetic energy k and its dissipation rate ϵ, are calculated from transport equations solved simultaneously with those governing the mean flow behaviour.

Enhancements of the simple method for predicting incompressible fluid flows
J. P. Van Doormaal,G. D. Raithby +1 more
TL;DR: The performances of SIMPLE, SIMPLER, and SIMPLEC are compared for two recirculating flow problems and several modifications to the method are shown which both simplify its implementation and reduce solution costs.

Variation in volatile organic compounds in the breath of normal humans.
Michael Phillips,Jolanta Herrera,Sunithi Krishnan,Mooena Zain,Joel Greenberg,Renee N. Cataneo +5 more
TL;DR: Two new findings were the comparatively small variation in total number of breath VOCs, and the presence of a 'common core' of breathVOCs in all subjects.

Comparison of the Piso, Simpler, and Simplec Algorithms for the Treatment of the Pressure-Velocity Coupling in Steady Flow Problems
TL;DR: The performance of the PISO, SIMPLER, and SIMPLEC algorithms for the treatment of the pressure-velocity coupling in steady flow problems is examined by comparing the computational effort required to obtain the same level of convergence in four test problems as discussed by the authors.
