Abstract, this paper; mention the complex dynamics systems structure and application in fluids mechanics. Shows the deterministic chaos in flow.
Keywords, Complex dynamics, fluid mechanics, deterministic chaos
In all engineering approaches, there is understanding the systems in nature. Benefiting humanity by reducing them to our daily life. Firstly, we can understand these systems. Then we need to analyse the systems and then make them usable. Some systems may be easier to analysis and make sense of than others. As the name suggests, complex dynamics systems are not this class easy to analyse and interpret. One of the complex system is Turbulence flow in fluids mechanics. Leonardo da Vinci (1452-1519) was the first one to use the word turbulence (turbolenza) to describe the vertical irregular motion of a fluid flow. As Physicist Werner Heisenberg says.“When I Meet God, I’ll ask him two questions: Why relativity? And why turbulence? I really believe he has an answer for the first’’. Turbulent flow is a still unsolved problem in physics. However in this century, thanks to development in electronics and thereby computer technology, we have become able to analyse in complex dynamics systems. In this way, we started to understand complex dynamics systems. Complex systems appear in many areas and formats; economics, health, engineering, game theory, butterfly affect, chaos, Van Gogh starry night…
The curiosity given by the unknown, complex structures have become one of the most studied and researched topics today. The subject of this article is turbulent flow in fluids mechanics, one of the complex structures that we do not fully understand its dynamics.
Complex systems can be defined as, consists of many subsystems (parameters), and can act as a whole system. When these subsystems considered as an individual. They can be analysed and concluded in a logical and understandable way. When these subsystems form a whole, they act within a logical framework. However, it is not easy to analyse and reach conclusions in an understandable way, on the contrary, it is a difficult, long and complex process. As a result of these analyses we conclude on sub-systems may not be valid for the supra- complex structure.
Fluids (liquids, gases, and plasmas) are defined as a materials that deforms continuously. Even if the balance of forces (static and dynamics loads) is provided. Fluid mechanics is the study of fluids behaviours at rest and in motion. In this paper, we discuss about structure of fluids in motion.
II. Purpose and Motivation
Turbulence flow appear a lot of place in our life. While we traveling by plane, we hear that ‘the plane will soon turn into turbulence, fasten your seatbelts’. Another thing is lamb in our house, phones, computers, oven all works with electricity. 14.2% of the electricity used in Italy obtained from hydroelectric power plants (2016). 15.6% of the electric energy generated around the world by hydroelectric power plants (2020). And these rates are increasing day by day. If we can fully analyse and interpret turbulence flow, we can increase energy efficiency here. If we understand turbulence flow, we will be able to find a solution. These and many other areas.
