Aerosols can be generated by physical processes such as nucleation, condensation and coalescence. To predict spatially varying statistical properties of such aerosols, e.g., the size distribution of the droplets, these processes must be captured accurately. We model nucleation using classical nucleation theory, whereas the condensational growth is captured with a molecular diffusivity model. Th...

In this first part of a two-part study, experiments were performed to investigate condensation of FC-72 along parallel, square micro-channels with a hydraulic diameter of 1 mm and a length of 29.9 cm, which were formed in the top surface of a solid copper plate. The condensation was achieved by rejecting heat to a counter flow of water through channels brazed to the underside of the copper plat...

In this study, nanofluid condensation and MHD flow analysis over an inclined and rotating plate are investigated respectively using Least Square Method (LSM) and numerical method. After presenting the governing equations and solving them by LSM, the accuracy of results is examined by the fourth order Runge-Kutta numerical method. For condensation, modeling results show that the condensate f...

The paper describes the results of numerical study of flow in the exhaust jet of turbofan engine CFM 56-3. Influence of computational domain decomposition, grid refinement and flow model on the jet flow field is discussed. Special attention is payed to simulation of nucleation and condensation processes in the exhaust jet. Growth of water clusters in the jet and cluster distribution in size are...

We study condensation of open string tachyons using renormalization group flow in the worldsheet field theory. This approach leads to a simple picture of the physics of the nontrivial condensate.

Abstract We show through laboratory experiments that the self-patterning of a thin clayey layer can be triggered by condensation. The natural sediment used in was highly polydisperse granular paste with smectite clay fine fraction. Under certain physicochemical conditions, condensation induces solid-to-liquid transition layer, resulting flow and formation band structures. These results suggest ...

The aim of this article is to thoroughly analyse the influence condensation models on modelling phenomena in transonic flow moist air. reason for study was fact that different are used by researchers obtain satisfactory results numerical modelling. tested herein differ nucleation rate formula and droplets growth equation. Four most often were selected detailed investigations. obtained from each...

Boiling-condensation heat transfer in ultrathin flat pipes are complicated and difficult to observe. In this study, a visualization experiment simulation analysis an limited enclosed space were carried out. Width of the ul?trathin was 1 mm, with anhydrous ethanol as working medium. The oriented vertically heating section on bottom cooling top. Flow characteristics photographed using high speed ...
