An Euler-type gas/particle two-phase flow numerical model is presented for simulating the deposition of particles of tens of microns. At this size range of particles, the dominant effect considered for deposition on the bottom surface is gravitational settling. The mass conservation equation for the particulate phase is developed and simulated to include convection, diffusion, and gravitational...

This paper presents a novel classifier to identify standard and sub-standard milk powder, which is built by support vector machines (SVM) and near infrared spectroscopy (NIR). The training set is composed of 38 samples and the testing set is composed of 12samples. The correct classification ratio of the training set is up to 100%, while that of the testing set is up to 100%. The result indicate...

For microfabrications of biochips with micro fluidic channels, a large number of microfabrication techniques based on silicon or glass-based Micro-Electro-Mechanical System (MEMS) technologies were proposed in the last decade. In recent years, for low cost and mass production, polymer-based microfabrication techniques by microinjection molding and micro hot embossing have been proposed. These t...

With the rapid development of economic, gypsum is widely used in casting and other industry areas. In this paper, the result is obtained that the performance of plaster mold is better when gypsum-water ratio is 0.5. If the composition of gypsum slurry mixture ( -hemihydrate, mullite powder, zirconium powder, reinforcing fibers) is mullite powder: zircon flour: enhancing fiber = 1:0.25:0.2:0.02-...

A pressurized continuous flow system using electromagnetic induction heating technique has been developed for the determination of trace and minor element content in biological samples by microwave induced plasma-optical emission spectrometry (MIP-OES). The system allows the continuous solubilization of samples at an optimized temperature of 120 °C and pressure of 3.5 bar in 40 min. A system wa...

THE P/M INDUSTRY has grown considerably in the past decade. As a result of this growth, more critical components in the automotive, aircraft, tooling, and industrial equipment industries are being considered for manufacture using this technology: This is placing increasingly stringent quality requirements on the final P/M part. Variations in part density, mechanical properties including strengt...

Near infrared (NIR) spectroscopy was used for estimation of powder blend homogeneity and manufacturing control of a medicinal product powder mixture containing active pharmaceutical ingredient (API). Aiming at initiating a Process Analytical Technology (PAT) activity, the first step was a stationary mode at-line evaluation. In this, the content of pharmaceutical active compound in the powder mi...

the dried fruit of terminalia chebula is widely used for its laxative properties. the objective of the present study was to examine the flowability and compressibility of terminalia chebula fruit powder, subsequently developing its tablet formulations by utilizing wet granulation and direct compression technology. initial studies on flowability and compressibility revealed that the fruit powder...

Wet granulation using foaming binder solution is a new approach of liquid delivery to create granules. This study compares wet granulation via foamed binder addition method and sprayed binder addition method by studying the kinetics of foam and drop penetrations into loosely packed powder beds. Foam and drop nucleation kinetics were compared by examining specific penetration time (penetration t...
