The issues addressed in this work concern the condensing steam flows as a flow of two-phase medium, i.e., consisting gaseous phase and dispersed form liquid droplets. character necessity to treat real gas make numerical modeling last turbine channels very difficult. There are many approaches known solve problem numerically, mainly based on RANS method with Eulerian approach. In paper, two were ...

An ultrasonic spray pyrolysis (USP) device consists of an evaporation and two reaction zones equal length, into which aerosol with a precursor compound enters, where nanoparticles are formed in the final stage. As part this research, we simulated geometry side inlet, gas (H2) enters tube by using numerical methods. Mixing carrier (N2) occurs at entry H2. In initial part, performed theoretical c...

The design of high-speed railway lines (HSR) requires mandatory consideration loads from the aerodynamic interaction a moving train, air environment and infrastructure facilities, acting both on structures train itself. Software systems computational fluid dynamics are most expedient to determine nature intensity load. To find optimal approach modelling processes between environment, as well as...

BACKGROUND Layered hydroxides salts (LHS), a layered inorganic compound is gaining attention in a wide range of applications, particularly due to its unique anion exchange properties. In this work, layered zinc hydroxide nitrate (LZH), a family member of LHS was intercalated with anionic ciprofloxacin (CFX), a broad spectrum antibiotic via ion exchange in a mixture solution of water:ethanol. ...

Objective(s):Cefixime (Cfx), is a semi-synthetic third-generation oral cephalosporin antibiotic that is prescribed for the treatment of susceptible infections. There are some procedures for the determination of Cfx in pharmaceutical formulations and biological samples. Herein a spectrofluorimetric method was proposed for Cfx determination based on the fluorescence quenching of terbium-danofloxa...

The improvement of wave generation in numerical tanks represents the key factor ocean engineering development to save time and effort research concerned with energy conversion. For this purpose, paper introduces a simulation method generate both regular irregular waves using Flap-Type maker. A 2D tank model is constructed beach technique, independence slope tested reduce reflections. different ...

Abstract A novel method to mitigate the rotating vortex rope is investigated numerically on a propeller turbine using ANSYS CFX. Pulsating momentum injected in horizontal plane diffuser cone from four evenly spaced jets. Three mitigation strategies are tested; M1 which perpendicular axial flow direction, M2, exhibit 12 degree angle against tangential velocity cone, and finally M3, same as M2 bu...

The electric submersible pump (ESP) is a centrifugal with several stages. It's dependable and efficient industrial lifting tool for different amounts of fluids, it's known its adaptability reliability. Electric pumps are commonly used in onshore oil wells, as well underground pumping other applications. pump's efficiency evaluated under the control various rotational speeds. CFD approach this a...

Centrifugal pump is widely used and plays an important role in national economy. However, according to plenty of engineering practice model tests, it indicated that the clearance between impeller cover parameter for leakage loss hydraulic efficiency. In this paper, a single stage centrifugal was selected study influence on performance through combination experiment numerical simulation. Commerc...
