The paper proposes a solution for the numerical simulation of the <sup>15</sup>N isotope distributed parameter separation process. In order to simulate the separation process, the matrix of partial derivatives of the state vector method, associated with Taylor series, is used. Also, an alternative form of a partial differential equation, of second order… (More)

In this paper, a variant for the pH control of the residual water from a foundry is presented. The blunting process of the residual water, being a distributed parameters one, is modeled using equations with partial derivatives. For the numerical simulation is used a method based on the matrix of the partial derivatives of the state vector (Mpdx) associated… (More)

For a functionally metallurgical rotary hearth furnace plant, a modeling and numerical simulation method is presented, based on the matrix of partial derivatives of the state vector M <inf>pdx</inf>, associated with Taylor series. There are marked out the advantages and the limits of the method, in the perspective of using it in the temperature control… (More)

The paper presents a possible version of systemic approach to model and simulate linear, time invariant processes, highlighting the unitary and systematized character of the procedure. The results can be extended for a large and diversified category of processes, with specific applications of control systems.

The kinetics of reaction between Cu<sup>2+</sup> and S<sub>2</sub>O<sub>3</sub> <sup>2-</sup> and formation of an intermediate complex, CuS<sub>2</sub>O<sub>3</sub>, are investigated. The kinetics of fading away of the color of this complex has been traced spectrophotometrically using a stopped-flow apparatus. The experimental reaction order is consistent… (More)

In this paper, a solution for the pH control of the residual water is presented. The blunting process is treated as a distributed parameter one, its model being expressed using equations with partial derivatives. The modeling-simulation procedure is based on the matrix of partial derivatives of the state vector associated with Taylor series, method that… (More)

A solution for the pH control of the residual water in an industrial blunting system is proposed. The technological process associated to the blunting system is decomposed in four sub-processes connected in series and in parallel, each of them being a distributed parameter one. The mathematical models of the sub-processes are expressed using partial… (More)

This paper has an informal character. It is referring to distributed parameter processes whose analogical modeling and numerical simulation can be complex and laborious. In these cases, the following compromise can present a major interest: - the determination of some approximating solutions, relatively simple, but sufficiently close to the phenomena… (More)
