Turbulent Compressibilty of Protogalactic Gas
The star formation rate in galaxies should be related to the fraction of gas that can attain densities large enough for gravitational collapse. In galaxies with a turbulent interstellar medium, this fraction is controlled by the effective barotropic index γ = dlogP/dlogρ which measures the turbulent compressibility. When the cooling timescale is smaller than the dynamical timescale, γ can be ev...
متن کاملHelium Absorption by Protogalactic Gas
We present a new, high resolution HST/GHRS spectrum of quasar Q0302003, and use the He Lyman-α absorption, together with a high resolution Keck spectrum of the HI Lyman-α forest, to probe the distribution and ionization state of the protogalactic foreground gas at z ≈ 3.3. Within ≈ 4000 km/sec of the quasar redshift the spectrum shows a substantial flux (τ ≈ 1) with “He Lyman-α forest” absorpti...
متن کاملThe Stabilizing Effect of Compressibility in Turbulent Shear Flow
Direct numerical simulation of turbulent homogeneous shear ow is performed in order to clarify compressibility e ects on the turbulence growth in the ow. The two Mach numbers relevant to homogeneous shear ow are the turbulent Mach number Mt and the gradient Mach number Mg . Two series of simulations are performed where the initial values of Mg and Mt are increased separately. The growth rate of...
متن کاملHigh-resolution PIV analysis of compressibility effects in turbulent jets
An investigation on the compressibility effects arising into the near field of turbulent jets operated at high Reynolds number at Mach numbers M=0.3, 0.9 and 1.1 (under-expanded regime) is carried out with twocomponents planar PIV experiments with high resolution cameras. The arrangement of the PIV system allows for mapping out the flow field with a vector pitch equal to 0.17mm along the stream...
متن کاملEstimation of Gas Mixture Compressibility Factor and Viscosity based on AI and Experimental DataEstimation of Gas Mixture Compressibility Factor and Viscosity based on AI and Experimental Data
Compressibility factor and viscosity of natural gasses are of great importance in petroleum and chemical engineering. To calculate the natural gas properties in the pipelines, storage systems and reservoirs, the exact values of gas compressibility factor and viscosity are required. A new method that allows accurate determination of compressibility factor and gas viscosity for all types of: swee...
