Evolution of Primordial Protostellar Clouds —quasi-static Analysis—
The contraction processes of metal-free molecular clouds of starlike mass (or cloud cores) are investigated. We calculate radiative transfer of the H2 lines and examine quasi-static contraction with radiative cooling. Comparing two time-scales, the free-fall time tff and the time-scale of quasi-static contraction tqsc (∼ tcool, the cooling time) of these cores, we find that the ratio of the two...
متن کاملCollapse of Primordial Clouds
We present here studies of collapse of purely baryonic Population III objects with masses ranging from 10M⊙ to 10 6M⊙. A spherical Lagrangian hydrodynamic code has been written to study the formation and evolution of the primordial clouds, from the beginning of the recombination era (zrec ∼ 1500) until the redshift when the collapse occurs. All the relevant processes are included in the calcula...
متن کاملThreshold-based quasi-static brittle damage evolution
We introduce models for static and quasi-static damage in elastic materials, based on a strain threshold, and then investigate the relationship between these threshold models and the energy-based models introduced in [17] and [15]. A somewhat surprising result is that, while classical solutions for the energy models are also threshold solutions, this is not the case for nonclassical solutions, ...
متن کاملYoung-measure Quasi-static Damage Evolution
An existence result for the quasi-static evolution of incomplete damage in elastic materials is presented. The absence of gradient terms in the damage variable causes a critical lack of compactness. Therefore, the analysis is developed in the framework of Young measures, where a notion of solution is defined, presenting some improvements with respect to previous contributions. The main new feat...
متن کاملQuasi-Static Numerical Simulation of Missile Staging
In this study, the missile staging process by implementing a side-injected jet is simulated numerically. The problem is considered to be axisymmetric and the thin shear layer approximation of Navier-Stokes equations along with an algebraic turbulence model is used in a quasi-static form for the calculations. The free stream corresponds to a very high altitude flight condition with a Mach number...
