Microencapsulation is a process in which solid, liquid or gas components are covered with a septum.The present study has focused on the effect of stirring to produce ferric saccharide capsules withalginate coating applying the coacervation method so that we can obtain the best capsules forfortification of hydrated and dehydrated food products. At first, three methods, including stirrer,ultra-so...

In this paper, overall heat transfer coefficient and friction factor of water based γ-Al2O3 nanofluid in a double tube counter flow heat exchanger have been measured experimentally under turbulent flow condition. For better dispersion of γ-Al2O3 nanoparticles in distilled water, magnetic stirrer and ultrasonic vibrator (with a power of 240 kW and frequency of 35 kHz) were implemented. The stabi...

This study examined the effect of sonication on FTIR and stability at various temperatures in water-based lubricants with a mixture Carboxymethyl Cellulose (1wt%) Uncaria Gambir extract (1wt% 2wt%). The sample was prepared by mixing two materials into distilled water using magnetic stirrer sonicator time variations 5 10 minutes. Before mixing, solution is first centrifuged to remove dregs powde...

The article presents an approach to the development of mathematical models non-sinusoidal and dual-frequency power supply for a linear induction MHD machine metallurgical purposes. issues construction numerical modeling modes three-phase inductor liquid aluminum stirrer are considered. Reduction losses is ensured by use toothless design inductor. absence steel teeth reduces saturation magnetic ...

This study aims to evaluate the effect of fluid flow rate on effectiveness radiator performance by using nanofluid consisting a mixture raw water with nano silica (SiO2) particles. The research was initiated testing material morphologically Scanning Electron Microscope (SEM) aim knowing its microstructure. Next, mix nanoparticles ratio 0.5%, processed magnetic stirrer for 8 hours and precipitat...
