The importance of air bubble dynamics in liquid is some phenomena like chemical and biochemical processes refinery units. 2D Volume Fluid (VOF) method together with the CFD technique were employed for simulating. dynamic meshing used to simulate hydrodynamics rising water column via User Defined Function (UDF) code C++ environment was developed evaluate through column. a stagnant has been consi...

The hydrodynamics of the waterjet-propelled ship is a challenging issue due to sophistication waterjet system geometry as well waterjet–hull interaction. In current study, three different propulsion models, namely, multiple reference frame (MRF) model, sliding mesh model and body-force are utilized simulate self-propulsion model. A based on User-Defined Function (UDF) ANSYS Fluent platform prop...

In this study, three-dimensional steady-state non-transferred arc plasma torch was investigated by computational fluid dynamics (CFD) method with user defined function (UDF). Two-equation current density profile was developed to simulate the complex plasma flow inside the torch. The effect of asymmetric distribution of current density (ADCD), particularly the deviation distance (distance betwee...

The distribution of velocity, sludge, and dissolved oxygen in a full-scale anaerobic-anoxic-oxic (A2/O) oxidation ditch was numerically simulated under three rotation speed scenarios. viscosity settling rate activated sludge were defined through user-defined function (UDF), the phase calculated using mixture multiphase flow model. Dissolved (DO) set as source (UDS) its generation consumption ra...

Abstract This paper aims to reduce the wind resistance of self-designed offshore tourism platform by optimizing its superstructure, and a transparent shape design is finally suggested. A numerical simulation was performed calculate load on test effect reduction. Two original scale models (sealed transparent) were established in accordance with requirements. The uses FLUENT software combined bui...

We investigated the transferability of 20 Fragaria vesca microsatellite primer pairs to 13 Fragaria vesca accessions, six Fragaria species and ten commercially important species in Rosaceae. Genetic diversity studies were carried among 16 diploid Fragaria accessions using these polymorphic microsatellites. The average number of alleles amplified for a polymorphic locus was 4.7 with maximum bein...

Inspired by the cactus in nature, a cactus-like cross-sectional structure was proposed to achieve VIV suppression. The of elastically mounted cylinder realized based on ANSYS Fluent and User Defined Function (UDF). dynamic motion solved single-step time integration algorithms Newmark-β method. in-house code first validated studying 2DOF circular with small mass ratio over range U*=2~13, results...

1 Based on observations made with the NASA/ESA Hubble Space Telescope, which is operated by the Association of Universities for Research in Astronomy, Inc., under NASA contract NAS 5-26555. These observations are associated with programs #9803. 2 Observations have been carried out using the Very Large Telescope at the ESO Paranal Observatory under Program ID(s): LP168.A-0485. ABSTRACT A very la...

215 INTRODUCTION Sensor and Data Fusion The term “sensor and data fusion” refers to techniques that combine data from multiple sources to produce new information and inferences and achieve more complete, clear, precise, accurate, and timely estimates pstream data fusion (UDF) refers to the processing, exploitation, and fusion of sensor data as closely to the raw sensor data feed as possible. Up...
