Mathematical model of CFB boiler Model is able to simulate • change of fuel properties – composition and heating value – size distribution • conditions of additive desulfurization – limestone excess – limestone size distribution • mass and heat transfer – definition of mass and heat flows in furnace – fluidization

Mathematical model. The theoretical model accounting for the influence of capillary forces in multiphase filtration of immiscible fluids in porous media, developed in [710] introduced rheological relationships to determine the capillary forces. The full set of equations for the general case can be found in [7,9].

MATHEMATICAL MODELS IN ECONOMICS – Vol. II Mathematical Modeling in Agricultural Economics Richard E. Just ©Encyclopedia of Life Support Systems (EOLSS) study of agricultural policy became an important subdiscipline in agricultural economics. Accordingly, the discipline matured as .

{ Approximations of the mathematical model which lead to tractable calculations. { Numerical calculations on a computer. { For models that include randomness, Monte Carlo simulations using a (pseudo) random number generator. If the mathematical analysis is successful it will make predictions about the real world. These are then checked.

A number of mathematical models are available in the literature that attempt to describe the mechanism of transport of particles through membranes such as Brownian diffusion, inertial lift, shearinduced diffusion, flowing cake and surface transport, and cake layer models .

The mathematical description of the unit processes (coagulation, flocculation, filtration, sedimentation, adsorption) that take place during the operation of these reactors has been derived. The mathematical models enable to predict and determine the effectiveness of purification and reactors operation time.

process. It can be considered as an "engineering" model, resulting by a combination of mathematical models, avail able in literature, and empirical feedback [1]. Such approach is, sometimes, called "one and half dimensional": the Riser is discretized in vertical direction by simple cells, while a .

Jul 17, 2003· Numerous mathematical models have been developed to evaluate both initial and transient stage removal efficiency of deep bed filters. Microscopic models either using trajectory analysis or convectivediffusion equations were used to compute the initial removal efficiency. These models predicted the removal efficiency under favorable filtration conditions quantitatively, but failed to .

Equipment Selection Methodology Equipment selection is seldom based on rigorous equations or elaborate mathematical models. Where equations are used, they function as a directional guide in evaluating data or process arrangements. Projected results are derived most reliably from actual An Introduction to Liquid Filtration 11

In the mathematical model of the Chephren pyramid we developed, we assumed that the pyramid is a regular pyramid with a quadratic base. The height of the pyramid: h = 4k, the side of the base: a = 6k. Height of the sidewall of the pyramid: l = 5k (Egyptian triangle).

In rapid filtration the physical processes usually are dominating, while the biological processes are negligible. The mathematical relations between the filtration parameters are relatively well characterized. Various mathematical models of rapid filtration have been developed during the past decades. These models can be divided in two (Ives ...
