Measurements of mean axial velocity, and the corresponding normal stress are reported for the isothermal flow of air and for a combusting mixture of natural gas in an axisymmetric furnace enclosure with a coaxial burner. Temperature and wall heat flux measurements were also obtained for the combusting flow. The swirl number of the flow was 0.5. The measurements are compared with the results of a calculation procedure incorporating a two equation turbulence model and a one step reaction model. The combustion model allowed fuel and oxygen to coexist at the same place but not at the same time. The comparison indicates that the calculation procedure qualitatively represents the measurements but that quantitative differences exist. The argument is sufficiently close, however, to justify the use of the method for some design purposes.

AbstractWe have developed a detailed siphon flow model for coronal loops. We find scaling laws relating the characteristic parameters of the loop, explore systematically the space of solutions and show that supersonic flows are impossible for realistic values of heat flux at the base of the upflowing leg.

To bring out details in the fractured surface of a frozen sample in the freeze fracture/freeze-etch technique,the sample or part of it is warmed to enhance water sublimation.One way to do this is to raise the temperature of the entire sample to about -100°C to -90°C. In this case sublimation rates can be calculated by using plots such as Fig.1 (Talmon and Thomas),or by simplified formulae such as that given by Menold and Liittge. To achieve higher rates of sublimation without heating the entire sample a radiative heater can be used (Echlin et al.). In the present paper a simplified method for the calculation of the rates of sublimation under a constant heat flux F [W/m2] at the surface of the sample from a heater placed directly above the sample is described.
