چکیده
Abstract The paper presents numerical modelling of the liquid film spreading dynamics R21 (mol. fraction: 0.9) and R114 refrigerants mixture. We considered an outer flow along a round vertical cylinder at Reynolds number 104 various contact angles. simulation was performed in OpenFOAM software on basis volume fluid (VOF) method. have shown that wetting front deforms angles 30 50 degrees, regular jets form. At same time, it demonstrated angle 10 degrees has practically flat shape, but one may see some thickenings line front.

Film condensation on non-isothermal vertical plates
An analytical study is presented of the condensation of a pure saturated vapour on a cooled channel plate, including the interaction between the cooling liquid, the condensate and the vapour. The governing equations of co-, counterand cross-current condensation are derived, set dimensionless and solved in closed form. The resulting implicit expressions are evaluated numerically by iteration. In...

and lone-pair electrons of its oxygen atom attached to the various sites in the latter case. The absorbance of the a band increased until the BET monolayer capacity of 1.1 mmol g-' was reached but stayed constant above this water content. The reason for this result could be that these free OH groups exist only on the surface of adsorbed layers or may remain inside the layer without hydrogen bon...
متن کاملNumerical solution for film evaporation of a spherical liquid droplet on an isothermal and adiabatic surfacet
A numerical solution for the problem of film evaporation of a liquid droplet on a horizontal surface is presented. The droplets are small enough to be assumed spherical. Two principal cases are considered : (1) the horizontal surface is maintained at a constant temperature (case I), and (2) the surface is insulated while the ambience is hot (case II). The complete set of equations governing thi...
متن کاملLiquid Spreading under Nanoscale Confinement.
Dynamic atomic force microscopy in the noncontact regime is used to study the morphology of a nonvolatile liquid (squalane) as it spreads along wettable nanostripes embedded in a nonwettable surface. Results show that the liquid profile depends on the amount of lateral confinement imposed by the nanostripes, and it is truncated at the microscopic contact line in good qualitative agreement with ...
متن کاملStructure and dynamics of liquid iron under Earth’s core conditions
First-principles molecular-dynamics simulations based on density-functional theory and the projector augmented wave ~PAW! technique have been used to study the structural and dynamical properties of liquid iron under Earth’s core conditions. As evidence for the accuracy of the techniques, we present PAW results for a range of solid-state properties of lowand high-pressure iron, and compare them...
