Flow field analysis of grooved surfaces
International Journal of Environmental Science and Technology, 2018In the present study, two-dimensional turbulent flow over rectangular and octagonal grooves in a channel is analyzed numerically. Investigations are performed for two different Reynolds numbers, Re = 615 and 1230 in terms of velocity and temperature field.

Computerized flow field analysis: oriented texture fields
IEEE Transactions on Pattern Analysis and Machine Intelligence, 1992An approach to the solution of signal-to-symbol transformation in the domain of flow fields, such as oriented texture fields and velocity vector fields, is discussed. The authors use the geometric theory of differential equations to derive a symbol set based on the visual appearance of phase portraits which are a geometric representation of the ...

Flow field analysis of rudder in CFD
AIP Conference Proceedings, 2021This paper analysis the failure causes of the combat jet aircraft rudder which occurred during fight mission. A rudder sizing method is used to determine the size of rudder, ANSYS is used for flow analysis of rudder and pro-e is used to design the rudder. The longitudinal crack occurred from the corrosion pit and the inner surface of rudder was heavily

Analysis of plant ribosomes with asymmetric flow field-flow fractionation
Analytical and Bioanalytical Chemistry, 2013Ribosome profiling is a technique used to separate ribosomal subunits, 80S ribosomes (monosomes), and polyribosomes (polysomes) from other RNA-protein complexes. It is traditionally performed in sucrose gradients. In this study, we used asymmetric flow field-flow fractionation (AsFlFFF) to characterize ribosome profiles of Nicotiana benthamiana plants.

Flow field-flow fractionation: recent trends in protein analysis
Analytical and Bioanalytical Chemistry, 2010Flow field-flow fractionation (F4) is the gentlest flow-assisted separation technique for analysis of macromolecules. The use of an empty channel as separation device and of a second mobile phase flow as perpendicular field enable F4 to separate analytes under native conditions without any modification of their original structure.

Separation of mitochondria by flow field-flow fractionation for proteomic analysis
The Analyst, 2008Flow field-flow fractionation (FlFFF) has been utilized for size-based separation of rat liver mitochondria. Collected fractions of mitochondria of various sizes were examined by confocal microscopy, and mitochondria of each fraction were lysed and analyzed by two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) for the comparison of protein ...

Asymmetrical flow field-flow fractionation for the analysis of PEG-asparaginase
Talanta, 2016Monomethoxypolyethylene glycol L-asparaginase (PEG-ASNASE) is the PEGylated version of the enzyme L-asparaginase (ASNASE). Both are used for remission induction in acute lymphoblastic leukemia (ALL) and non-Hodgkin's lymphoma (NHL). The treatment control is generally carried out by performing activity assays, though methods to determine the actual ...

3D FLOW FIELD ANALYSIS OF A BANBURY MIXER
International Polymer Processing, 1992Abstract Banbury mixers are widely used in polymer processing. The flow field in the chamber of an internal mixer is difficult to analyze due to the complex geometry and transient character of the flow. In this work, a fluìd dynamics analysis package – FIDAP, using the finite element method was employed to simulate the flow patterns in a

Field flow fractionation in biomedical analysis
Biomedical Chromatography, 1991AbstractSamples of biomedical interest which have been analysed by field‐flow fractionation techniques are surveyed. The list begins with whole cells and microorganisms, going through viruses, nucleic acids, cell fragments and organelles, down to proteins and their aggregates.

Analysis of Peptides using Asymmetrical Flow Field-flow Fractionation (AF4)
Journal of Pharmaceutical Sciences, 2021While asymmetrical flow field-flow fractionation (AF4) has been widely used for separation of high molecular weight species and even particles, its ability to resolve lower molecular weight species has rarely been explored. Over the course of many projects, we have discovered that AF4 can be an effective analytical method for separating peptides from ...
