- Abstract
It is known that hydrodynamics is principally divided into fluid mechanics and aerodynamics, which is concerned with the fluidization of gases. Hydrodynamics can in principle be divided into hydraulic, aerodynamic, gas dynamics, meteorological dynamics, and the like. Since here in principle we are dealing with aerodynamics, then it should be emphasized that it is based on the mechanical laws related to air current. This means that we mainly deal with the fluidization of solid bodies by air, as well as the laws of fluidization of air within the pipe distribution network and ventilation and air conditioning channels. Concerning the design of air-conditioning distribution networks, many factors must be taken into account, one of which being the most accurate determination of the coefficient of resistance during the fluidization of air within the air-conditioning ducts and pipes. In addition, the paper will elaborate the method of determining the elasticity coefficient as an important parameter of economic statistics. Also emphasized is the role of statistical weighting and variance, as statistically significant quantities within the problem at hand. In relation to the metrics given in the paper, the role of the use of numerical methods is of particular importance. Otherwise, it is well known that numerical methods are actions for approximating, but sufficiently accurate, the calculation of problems when the search for the correct analytical solution is quite difficult. Otherwise the numerical methods can be divided into two groups, the basic and the derived ones. Basic numerical methods mean those actions that can be algorithmically and generally programmed without the direct need to know the field in which they are applied. In numerical compilation methods the actions to which the problem is addressed are based on the use of one or more basic methods. These methods can hardly be algorithmic without in-depth knowledge of the field in which they are used. The role of iterative methods, especially with respect to the solution of linear equation systems, should also be mentioned, when starting from some assumed values for the nonlinear vector, and then making the corrections so that the maximum calculation error is smaller, that a sufficiently small size of the same value. The number of calculations of operations in question is given previously and depends on the required accuracy of the solution. The problem of assigning the coefficient of resistance during the air current within the vent can also be deepened in terms of determining the function of the current, namely the complex potential. This is especially true for ventilated channels with more complex geometric shapes. Elaborating the complex potential in such cases enables not only the reduction of the number of current functions but also the reduction of the number of coordinates, respectively, thus reducing the number of variables. It should be emphasized that through the complex potential can be expanded the number of solutions to many practical problems. This is closely related to the problem of conformal reflections.
