Modification of flow and compressibility of corn starch using quasi-emulsion solvent diffusion method

Objective(s):The aim of this study was to improve flowability and compressibility characteristics of starch to use as a suitable excipient in direct compression tabletting. Quasi-emulsion solvent diffusion was used as a crystal modification method. Materials and Methods: Corn starch was dissolved in hydrochloric acid at 80˚C and then ethanol as a non-solvent was added with lowering temperature ...

Performance Prediction Modeling of Axial-Flow Compressor by Flow Equations

Design models of multi- stage, axial flow compressor are developed for gas turbine engines. Axial flow compressor is one of the most important parts of gas turbine units. Therefore, its design and performance prediction are very important. One-dimensional modeling is a simple, fast and accurate method for performance prediction of any type of compressors with different geometries. In this appro...

CFD Analysis of a Regenerative Pump for Performance Enhancement

Regenerative centrifugal pumps (RCP) are the subject of increased interest in industry as these pumps produce less noise, have low specific speed and are compact but capable of delivering high heads with stable performance characteristics. The regenerative flow pumps are essentially rotodynamic turbo machines capable of developing high pressure ratios within a single stage. This paper presents ...

Numerical Simulation of Cavitation in Mixed Flow Pump

The purpose of this study is to investigate the performance and three-dimensional behavior of the flow in a mixed flow pump and the way cavitation phenomenon is affected by different parameters such as fluid temperature, pump speed and flow rate. Computational fluid dynamic software FLUENT 6.3 was utilized to simulate the whole flow field of the pump. RNG k-ε model combined with standard wall f...
