Dropwise condensation of humid air over hydrophilic and hydrophobic surfaces is numerically investigated using a phenomenological, Lagrangian model. Mass flux through droplets free surface predicted via vapor-diffusion Validation with literature experimental data successfully conducted at different humidities velocities. The accuracy the implemented model compared standard analogy between conve...

The effects of a sorption-controlled, monolayer-forming surfactant on a drop deforming in an extensional flow are studied numerically. Scaling arguments are presented for drops of 1 cm and 1 µm, indicating the applicability of these results. For all simulations, when mass transfer is slow compared to surface convection, the insoluble limit is recovered; when mass transfer is rapid, the drop beh...

In a previous paper, pressure drop, flooding and mass-transfer characteristics of a novel pilot-scale distillation column called spinning cone column (SCC) were presented. Here, we present the result of comparison of mass-transfer efficiencies of SCC and structured packing. Comparison of SCC and structured packing mass-transfer characteristics show that the gas and liquid-side height of transfe...

Curcumin (CUR) is the active curcuminoid with many physiological, biochemical, and pharmacological properties. Solubility and stability of CUR is the limiting factors for realizing its therapeutic potential. Bovine β-casein is an abundant milk protein that is highly amphiphilic and self-assembles into stable micellar nanoparticles in aqueous solution. β-Casein nanoparticle can solubilize CUR mo...

in this research, papaya slices with dimensions of 0.5×2×5 cm3 were dried at 45 °c using a cabinet dryer in which drying air velocity and relative humidity were 0.9 m/s and 30%, respectively. the moisture diffusion coefficient of papaya was determined in this drying condition. mass transfer equation with its boundary conditions was solved based on finite difference method. finally, coefficient ...

Background: Creating a new berberine liposome with high encapsulation efficiency and slow release formulation in the treatment of cancer is a new issue. Therefore, the aim of current study was to develop slow release berberine-containing nanoliposome for delivery to bone cancer cells Saos2. Materials and Methods: In this experimental study, after synthesis nanoliposomal formulation, physical p...
