The aim of this study is to investigate the thermal performance water-based Carbon Nano Material (CNM) nanofluids, particularly in convective heat transfer coefficient (h) parameter, and analyze effects nanoparticle concentration flow rate on an experimental system. To achieve this, researchers prepared nanofluid through a 2-step method. In first step, we mixed nanoparticles with base fluid usi...

Fluid mixing is a crucial and challenging process for microfluidic systems, which are widely used in biochemical processes. Because of their fast performance, active micromixers that use stirrer blades are considered for biological applications. In the present study, by using a robust and convenient Incompressible Smoothed Particle Hydrodynamics (ISPH) method, miscible mix...

kinetic study of epoxidation of unsaturated ketone of mesityl oxide was studied by usinghydrogen peroxide in the presence of dodecyltrimethyl ammonium bromide (dtab) as aninverse phase transfer catalyst. the reaction was carried out in the two-phase media of waterheptanewith 1:1 ratio in 25 °c. it was found that the order of reaction for mesityl oxide forketone concentration in the range of 0.0...

In this paper, the electromagnetic field distribution inside a jet engine is studied through full wave analysis. Results are statistically analyzed by comparisons to the models used for the reverberation chamber with a mechanical mode stirrer. The jet engine is simulated as an open cylinder containing one set of rotating blades by using ‘Ansys R ©HFSS’. A simple Hertzian dipole illuminates the ...

Liquid food can likely cause accidental ingestion in patients with dysphagia. This study proposes a handheld stirrer-type rotational viscometer that be used the kitchen or at meals for A novel is proposed considering rotation speed of stirrer inversely proportional to viscosity fluids stirred. We adopt sensorless control strategy. use small brush-type DC motor, which functions as rotary actuato...

Rice straw is a very abundant lignocellulose agricultural waste in Indonesia. This generally used as much 31% for animal feed, 7% industrial purposes, and 62% burned rice fields. burning can cause respiratory disorders such ARI cancer. Lignocellulose itself polysaccharide consisting of lignin, cellulose, hemicellulose. The lignin content be the production edible film, so to increase its usefuln...
