The metastable zone width (MSZW) and induction time of CoSO4 in the presence H2SO4 were measured at various operating conditions by polythermal isothermal methods, respectively. Raman spectroscopy UV–Vis have been successfully adopted for measuring solubility CoSO4. nucleation parameters estimated with a self-consistent Nývlt-like approach classical 3D theory approach. results show decrease an ...

This work is focused on exploring the flow and heat transfer capabilities for slotted axisymmetric cavity configurations synthetic impinging jets; jet enclosed between two isothermal parallel plates, into top hot plate. Numerical simulations using Arbitrary Lagrangian-Eulerian formulation of Navier-Stokes equations are performed Reynolds numbers 50, 300 500 a formation criteria 3. The pattern f...

in the present work, the interaction of three water soluble porphyrins, tetra (p-trimethyle) ammoniumphenyl porphyrin iodide (tapp) as a cationic porphyrin, tetra sodium meso-tetrakis (p-sulphonatophenyle) porphyrin (tspp) as an anionic porphyrin and manganese tetrakis (p-sulphonato phenyl)porphinato acetate (mntspp) as a metal porphyrin, with dna have been studied by isothermaltitration microc...

An isothermal tokamak, Isomak, is investigated to demonstrate that nearly exact, rigidly toroidally rotating Maxwellian solutions exist for both the ions and the electrons. For the ions this Maxwellian solution is valid in the limit in which unlike collisions of the ions with the electrons are weak and the induced electric field unimportant, while for Maxwellian electrons unlike collisions can ...

With the increasing need to utilize carbon dioxide, fixed-bed reactors for catalytic hydrogenation will become a decisive element modern chemicals and energy carrier production. In this context, resilience flexibility changing operating conditions major objectives design operation of real industrial-scale reactors. Therefore steady-state multiplicity stability are essential measures, but so far...

Mixing ventilation in airplane cabins is driven by overhead supply jets, which may be directed towards each other, interact and merge before entering the passenger area. Although many studies already investigated cabin mixing ventilation, detailed knowledge on fundamental flow components (i.e. interaction zone, merged jet secondary flows) rather scarce, but can useful to obtain new insights int...

In order to explore the rising and diffusing path of an underwater thermal jet temperature variation each water layer in typical ocean thermohaline stratified environment, a three-dimensional mass-heat transport model weak environment was built by using Detached-Eddy Simulation method Volume Fluid simulate whole life evolution process different depths, difference, flow rate.
