Mass transfer in tidally unstable compact binaries
The 2001 outburst of WZ Sagittae has shown the most compelling evidence yet for an enhancement of the mass transfer rate from the donor star during a dwarf nova outburst in the form of hot-spot brightening. I show that even in this extreme case, the brightening can be attributed to tidal heating near the interaction point of an accretion stream with the expanding edge of an eccentric accretion ...
متن کاملNumerical Investigation of Turbulent Mass Transfer in a 90° Bend
This paper presents a numerical study of local mass transfer coefficients in a 90° bend using the RNG version of k–e model to include the influence of curvature on the turbulent transport. Simulations were performed for flow through a 90°, 3-D bend for Reynolds numbers of 13500, 90000, and 390000, Schmidt numbers of 2.53 and 700 and curvature ratios of 1.5, 2, and 2.5. The differences betwe...
متن کاملA Theoretical Mass Transfer Approach for Prediction of Droplets Growth Inside Supersonic Laval Nozzle
Proper estimation of droplet growth rate plays a crucial role on appropriate prediction of supersonic separators performance for separation of fine droplets from a gas stream. Up to now, all available researches employ empirical or semi-empirical correlations to define the relationship between droplet growth rate (dr/dt) and other operating variables such as temperatures (T and TL), Pressure (P...
متن کاملFlow Analysis Heat and Mass Transfer in a Room
This reports the study on the flow behaviour, heat transfer and contamination distribution in a room. For this purpose the 3-D incompressible Navier-Stokes equations, energy equation and a mass transfer equation which model the concentration of contamination have been applied. For turbulence simulation the two equation standard k- turbulence model was employed. By means of SIMPLE algorithm the...
متن کاملA rare case of bilateral pelvic mass
Absract A case of 69- year-old woman with large pelvic mass and ascites is reported in this paper. With the exception of mild pelvic pain and a Pelvic mass in pelvic , she had no symptom or sign . All routine and hormonal Lab tests and tumor marker's were normal. The MRI revealed a large mass in anterosuperior of uterus, and left ovary was situated in neighborhood of pelvic mass.Her Uterus nor...
