Unsteady Aerodynamics of Low-Pressure Steam Turbines Operating Under Low Volume Flow

Peter Ott, Benjamin Megerle, Ivan William McBean

Non-synchronous excitation under low volume operation is a major risk to the mechanical integrity of last stage moving blades (LSMBs) in low-pressure (LP) steam turbines. These vibrations are often induced by a rotating aerodynamic instability similar to r ...

Air handling unit condensate in tropical and subtropical climates - Why waste down the drain?

Dusan Licina

In tropical and subtropical regions, air-conditioning is employed throughout the year, which poses a significant challenge to the designer in reducing its energy consumption. Buildings in these regions would have latent load that is large enough throughout ...

Energy and water conservation from air handling unit condensate in hot and humid climates

Dusan Licina

This study investigates the potential for energy and water sustainability in hot and humid climates by utilizing the condensate captured from large dedicated air handling units (AHUs) for pre-cooling outdoor air in another AHU and subsequently offsetting c ...

Transient Simulation of Two-Phase On-chip Liquid Pump Cycle for Processor's Cooling

John Richard Thome, Jackson Braz Marcinichen, Nicolas Lamaison

Transient modeling and regulation of a two-phase on-chip liquid pump cooling cycle is studied. The purpose is to cool down multiple micro-processors in parallel and a set of memories, DC/DC converters in series. The cycle will be incorporated in a blade/dr ...

Two-phase flow patterns in U-bends and their contiguous straight tubes for different orientations, tube and bend diameters

John Richard Thome, Ricardo Lima

In two-phase systems there are many singularities in piping systems, one of which in particular are U-bends (also called 180 degrees return bends or U-tubes) found very often in air conditioning coils, refrigerant systems, etc. Contrary to the literature c ...

Verification of stochastic models of window opening behaviour for residential buildings

Darren Robinson, Frédéric Haldi

Based on the analyses of data from two distinct measurement campaigns conducted in residential indoor environments in Japan and Switzerland, we identify the specificities of occupants' behaviour with respect to their interactions with windows, including th ...

EXPERIMENTAL STUDY ON FLOW BOILING HEAT TRANSFER OF MULTIPORT TUBES WITH R245fa AND R1234ze(E)

John Richard Thome, Bruno Agostini, Farzad Vakili Farahani

This article presents an experimental study of upward flow boiling heat transfer in multiport tubes. Usually, multiport tubes are utilized horizontally in automotive and air-conditioning systems while here there is interest in vertical flow as part of a tw ...

Contribution du modèle LiDAR pour la caractérisation de surfaces urbaines et le paramétrage de modèles de simulation des flux atmosphériques en pollution de l'air

Florent Christian Jacques Cornuet

Afin de simuler la pollution de l'air en milieu urbain, les modèles actuels de flux atmosphériques utilisent comme input des classes de couverture du sol obtenues avec l'aide d'images satellite standards (e.g. Landsat ETM+). Ces surfaces urbaines classifié ...
