Mathematical Model for the Separation Behavior of Low-Shock Separation Bolts Article in Journal of Spacecraft and Rockets 55(2):1-14 · May 2018 with 29 Reads DOI: 10.2514/1.A34090

The flow behavior of the same powder between applications may be quite dif-ferent. For example, a powder that flows well through a bin may flow poorly at the tablet press. Currently, no universal mathematical model exists to predict powder flow behavior in every situation, nor is such a universal model for powder flow anywhere in sight. A ...

Flocking behavior is the behavior exhibited when a group of birds, called a flock, are foraging or in flight. There are parallels with the shoaling behavior of fish, the swarming behavior of insects, and herd behavior of land animals.. Computer simulations and mathematical models which have been developed to emulate the flocking behaviors of birds can also generally be applied to the "flocking ...

Oct 19, 2007· An improved mathematical model to simulate the particle and flow behavior in a coal-washing spiral has been developed. The modeling framework addresses three main components of the spiral system: (i) geometry of the spiral and its trough, (ii) fluid motion along the curvilinear path of the spiral and (iii) principal forces acting on a particle incorporating "Bagnold effect".

which we think about and make models to describe how devices or objects of interest behave. There are many ways in which devices and behaviors can be described. We can use words, drawings or sketches, physical models, computer pro-grams, or mathematical formulas. In other words, the modeling activity

Its separation behavior, however, is complicated and not understood well because the separation happens within a few milliseconds through complex mechanical interaction. In this Paper, a mathematical model is established to predict the separation behavior of a ball-type separation bolt.

A mathematical model is a description of a system using mathematical concepts and language.The process of developing a mathematical model is termed mathematical modeling.Mathematical models are used in the natural sciences (such as physics, biology, earth science, chemistry) and engineering disciplines (such as computer science, electrical engineering), as well as in the social sciences (such ...

of the adsorptive separation of carbon dioxide for optimizing design and operating conditions. A com-prehensive mathematical model consists of coupled partial differential equations distributed over time and space that describe material, energy, and the momentum balances together with transport rates and equilibrium equa-tions.

Mathematical models of mass transport for all operation modes are based on the following assumptions: isothermal conditions, the absence of a pressure gradient in the channel along the membrane, ideal gas behavior of components, and constancy of membrane permeability.

Mathematical Model Two separation ratios were proposed to describe the source of separation activity. These were the incipient separation ratio (W 0) for behavior generation and the stable separation ratio (W) for behavior stability: W 0 f F,K g E c,E n,H 0 F K P max (1) W 0 W 0 TW 0 W t 0 TW 0 W t (2) where f(F,K) is a function of toggle ...

A Mathematical Model is an abstraction of a real-life scenario, system or event that uses mathematical language to describe and predict the behavior, dynamics and evolution of said scenario, system or event. Mathematical Modelling is thus the step...

Mathematical Model for Leukocyte Migration in Prosthetic Materials Ana Moreno, Shawn R Mailo, Sheng-Hsiou Hsu, Jahir Gutierrez Page 3 L Also, we assume the site of infection is at the right boundary and leukocytes would move

Jul 21, 2005· The use of mathematical models in the experimental analysis of behavior has increased over the years, and they offer several advantages. Mathematical models require theorists to be precise and unambiguous, often allowing comparisons of competing …

A mathematical model has been developed to characterize the separation behavior of a typical high ash coal in a spiral. The modeling framework consists of parametric representation of geometry of the spiral and its trough, particulate flow along the helical path and principal forces acting on a …

A complex mathematical model of coupled ordinary scale-up from laboratory to plant scale, it is essential to differential equations (ODEs) is formed during the use mathematical models, whose numerical parameters are mathematical modeling of membrane gas separation based completely determined by the plant setup, its geometry on cross flow.

dynamic behavior during the separation process. One opportu-nity to describe these transient effects is the dynamic modeling by interconnecting a defined number of compartments. The presented approach models the transient behavior of the sepa-ration by considering the residence time distribution, sediment buildup, and solids transport.

Jun 10, 2019· As a result of this complexity, coupling experimental models with mathematical models presents a robust way to mimic, quantify, and describe tumor behavior. Furthermore, mathematical models can be ...

Comparison of Some Key Parameters Contributing to Lignocellulosic Fiber Deformation Behavior by a Mathematical Model Deformation behavior is an important fundamental characteristic of lignocellulosic fibers; it affects the application range of fiber materials and the properties of fiber-based products.

A "Multi-component Progressive Cell Balance" approach has been applied to characterize the gas separation of the radial crossflow hollow fiber membrane module. The mathematical model is an indispensable tool to evaluate the separation performance of membrane material towards different components. The approach is required to be implemented since there is scarcely available mathematical ...
