Condensation of a vapor bubble in submicrometer container.

Condensation of a spherically symmetric submicrometer size vapor bubble is studied using diffuse interface hydrodynamic model supplemented by the van der Waals equation of state with parameters characteristic for argon. The bubble, surrounded by liquid, is held in a container of constant volume with temperature of the wall kept fixed. The condensation is triggered by a sudden rise of the wall t...

Numerical Simulation and Parametric Study of Forced Convective Condensation in Vertical Channel

Forced convective condensation in vertical channel is investigated numerically. The condensation boundary layers that occur due to temperature difference between the walls and saturation temperature of steam is simulated by the volume of fluid (VOF) method. The effect of variations in the hydraulic diameter, steam velocity, Re number and temperature difference between the wall and saturation te...

Numerical simulation of single bubble rising in vertical and inclined square channel using lattice Boltzmann method

A lattice Boltzmann equation (LBE)model based on the Cahn–Hilliard diffuse interface approach is used to investigate thedynamics of a bubble rising in a vertical and inclined square channelwith large density and viscosity ratios. Deformation parameter D, film thickness d, and terminal velocity Ut of the bubble are interrelated quantities which depend on non-dimensional numbers such as Bond numb...

Optimal Design of Open Channel Sections Using PSO Algorithm

This paper applies an evolutionary algorithm, the particle swarm optimization (PSO), to design the optimum open channel section. Depth, channel side slope and bottom width are considered as the variables for rectangular, triangular and trapezoidal channels, respectively. The objective function is minimizing the construction cost of the channel section. MATLAB software is used for programming an...

Shear Stress in Smooth Rectangular Open-Channel Flows

The average bed and sidewall shear stresses in smooth rectangular open-channel flows are determined after solving the continuity and momentum equations. The analysis shows that the shear stresses are function of three components: (1) gravitational; (2) secondary flows; and (3) interfacial shear stress. An analytical solution in terms of series expansion is obtained for the case of constant eddy...
