THE MODELING OF THE FLOW OF WATER THROUGH THE BOSPORUS JOHNS, B; OGUZ, T (1990-03-01) A numerical model is developed for the exchange of water between the Black Sea and the Marmara Sea through the Bosphorus. An essential part of the modelling procedure is the use of a turbulence energy equation in a scheme of turbulence parametrization. The simultaneous application of a transport equation for the salinity leads to a turbulence suppression term associated with the existence of a strongly stable vertical salinity stratification. Experiments are performed that show how a prescribed difference b...
The analysis of cooling curves for grey cast iron and its mechanical properties Kalkanlı, Ali; GULDUR, H (2003-07-01) Thermal analysis can be utilized to reveal the total graphite nucleated in cast irons by correlating the integrated areas under the cooling curves and graphite areas of a cast iron sample measured using an image analyzer. The aim of this study is to determine the effect of varying amounts of inoculants on the thermal analysis of grey cast iron by observing the changes in the shape of the cooling curves. DeltaT values, i.e. the observed undercooling before recalescence, can be correlated to the changes in th...
