In the drinking water treatment plant involves a significant component i.e., coagulation, which distributed coagulants vastly and equally through rapid stirring for destabilizing colloids suspended particles in raw water. plants, coagulation units are often classified into mechanical hydraulic coagulation. This study aimed to discover use of in-line static mixers as designing Duren Seribu II Dr...

We report on the first THz balanced mixer/upconverter using a Schottky diode MMIC chip. Using an optically pumped laser at 1562 GHz as an LO source with a coupled power of about 1 mW, and 1 mW input at an IF frequency of 10 GHz, we obtained a sideband output power of 23 uW (sum of two sidebands). As a mixer, at an LO of 1621 GHz, we obtain a conversion loss of 12.4 dB DSB and a noise temperatur...

A few years ago, the process of selecting a mixer for most applications was straightforward. When increased demand required an increase in production, process engineers were naturally inclined to choose the type of mixer that had worked before in the same application. When they began talking to equipment manufacturers, their questions focused on capacity, auxiliary equipment, projected delivery...

This paper discusses the design and evaluation of the system MIXER (Moderating Interactions for Cross-Cultural Empathic Relationships), which applies a novel approach to the education of children in cultural sensitivity. MIXER incorporates intelligent affective and interactive characters, including a model of a Theory of Mind mechanism, in a simulated virtual world. We discuss the relevant peda...

The mixer chain on a graph G is the following Markov chain. Place tiles on the vertices of G, each tile labeled by its corresponding vertex. A “mixer” moves randomly on the graph, at each step either moving to a randomly chosen neighbor, or swapping the tile at its current position with some randomly chosen adjacent tile. We study the mixer chain on Z, and show that at time t the expected dista...

We have developed a microfluidic mixer for studying protein folding and other reactions with a mixing time of 8 mus and sample consumption of femtomoles. This device enables us to access conformational changes under conditions far from equilibrium and at previously inaccessible time scales. In this paper, we discuss the design and optimization of the mixer using modeling of convective diffusion...

The gas–liquid vortex reactor (GLVR) has substantial process intensification potential for multiphase processes. Essential in this respect is the micromixing efficiency, which of great importance fast reaction systems such as crystallization, polymerization, and synthesis nanomaterials. By creating a flow taking advantage centrifugal force field, liquid can be intensified GLVR. Results show tha...

The gas-liquid flow behavior through a milli-scaled channel provided with staggered herringbone-like static mixer was investigated using high-speed recordings. For three different substance systems consisting of water, 5 wt % acetic acid in aqueous solution, and propylene glycol as liquid phase nitrogen gas phase, patterns their transitions were determined by analyzing image sequences the summa...

In microfluidics mixing of different fluids is a highly non-trivial task due to the absence of turbulence. The dominant process allowing mixing at low Reynolds number is therefore diffusion, thus rendering mixing in plain channels very inefficient. Recently, passive chaotic micromixers such as the staggered herringbone mixer were developed, allowing efficient mixing of fluids by repeated stretc...
