Introduction Conclusions References Tables Figures Back Close Full Screen / Esc Printer-friendly Version Interactive Discussion EGU Abstract In this technical note we present the exact form of the Zeldovich factor for heterogeneous nucleation on spherical pre-existing particles. We study the error caused by planar pre-existing surface approximations, which have been used in our earlier heterogeneous nucleation model and elsewhere in the literature. We also test the signif-5 icance of widely used approximations for cluster surface area and circumference. We conclude that the approximations do not affect the predicted onset saturation. Especially for small pre-existing particles the nucleation rates calculated with the exact and approximative models differ significantly.

The kinematic Sunyaev Zeldovich effect and transverse cluster velocities
The polarization of the CMBR scattered by galaxy clusters in the kinematic Sunyaev Zeldovich effect depends on the transverse velocity of the cluster. This polarizing effect is proportional to the transverse velocity squared, and so weaker that the change in intensity due to the radial motion in the kinematic effect. The value given by Sunyaev and Zeldovich, and which is frequently cited, under...
متن کاملStudying the Effect of Horizontal Drains on Stability of Heterogeneous and Homogeneous Earth Dams during Rapid Drawdown Condition
One of the main concerns to design earth dam is the stability of the upstream slope of the earth dam in phase of rapid drawdown. Confined pore water pressure reduces the effective stress in this mode, so possibility of the instability and slippage will be increased. The main goal of this research is to investigate changes in the pore water pressure by using horizontal drains in upstream slope o...
متن کاملThe effect of cluster magnetic field on the Sunyaev Zeldovich power spectrum
Precision measurements of the Sunyaev Zeldovich (SZ) effect in upcoming blank sky surveys require theoretical understanding of all physical processes with & 10% effects on the SZ power spectrum. We show that, observed cluster magnetic field could reduce the SZ power spectrum by ∼ 20% at l ∼ 4000, where the SZ power spectrum will be precisely measured by the Sunyaev Zeldovich array (SZA) and the...
متن کاملOn the Meaning and Inapplicability of the Zeldovich Relations of Magnetohydrodynamics
Considering a plasma with an initially weak large scale field subject to nonhelical turbulent stirring, Zeldovich (1957), for two-dimensions, followed by others for three dimensions, have presented formulae of the form 〈b〉 = f(RM )B 2 . Such “Zeldovich relations” have sometimes been interpreted to provide steady-state relations between the energy associated with the fluctuating magnetic field a...
متن کاملIMPORTANCE OF CLUSTER STRUCTURAL EVOLUTION IN USING X-RAY AND SUNYAEV-ZELDOVICH EFFECT GALAXY CLUSTER SURVEYS TO STUDY DARK ENERGY SubhabrataMajumdar
We examine the prospects for measuring the dark energy equation-of-state parameter w within the context of the still uncertain redshift evolution of galaxy cluster structure. We show that for a particular X-ray survey (Sunyaev-Zeldovich effect [SZE] survey), the constraints on w degrade by roughly a factor of 3 (factor of 2) when one accounts for the possibility of nonstandard cluster evolution...
