Special Issue Information

Dear Colleagues,

In modern research, many problems are characterized by complexity and dependence on multiple parameters. The entropy of a system is a direct measure of its complexity. Other complexity-related mathematical functions include the Hurst exponent, long-range correlation, fractals, stochastic processes, probability, and fuzzy probability. These models may be seen in various fields of science, such as physics, engineering, mechanics, biology, economics, and some more mathematical applications.

The aim of this Special Issue is to discuss, from both theoretical and applied points of view, the physical and engineering properties of the entropy- and complexity-based models arising in nature and applied sciences.

Topics of interest are given below, and papers related to these fields are welcome:

  • entropy and complexity of mathematical models with fractional and integer order;
  • new analytical and numerical methods in the analysis of problems where entropy and complexity are the main features;
  • entropy and complexity in computational methods for differential models;
  • entropy and complexity in engineering, fluid dynamics, and thermal engineering problems, as well as problems related to physics, applied sciences, and computer science;
  • deterministic and stochastic fractional order models;
  • entropy and complexity models in physics and engineering;
  • entropy and complexity in analytical and numerical solutions;
  • nonlinear dynamical complex systems;
  • entropic measure of epistemic uncertainties.

Some new perspectives are offered on the spectral and spatial structure of turbulent flows, in the context of conservation principles and entropy. In recent works, we have shown that the turbulence energy spectra are derivable from the maximum entropy principle, with good agreement with experimental data across the entire wavenumber range. Dissipation can also be attributed to the Reynolds number effect in wall-bounded turbulent flows. Within the global energy and dissipation constraints, the gradients (d/dy+ or d2/dy+2) of the Reynolds stress components neatly fold onto respective curves, so that function prescriptions (dissipation structure functions) can serve as a template to expand to other Reynolds numbers. The Reynolds stresses are fairly well prescribed by the current scaling and dynamical formalism so that the origins of the turbulence structure can be understood and quantified from the entropy perspective.

During manned space missions, an environmental control and life-support system (ECLSS) is employed to meet the life-supporting requirements of astronauts. The ECLSS is a type of hierarchical system, with subsystem—component—single machines, forming a complex structure. Therefore, system-level conceptual designing and performance evaluation of the ECLSS must be conducted. This study reports the top-level scheme of ECLSS, including the subsystems of atmosphere revitalization, water management, and waste management. We propose two schemes based on the design criteria of improving closure and reducing power consumption. In this study, we use the structural entropy method (SEM) to calculate the system order degree to quantitatively evaluate the ECLSS complexity at the top level. The complexity of the system evaluated by directed SEM and undirected SEM presents different rules. The results show that the change in the system structure caused by the replacement of some single technologies will not have great impact on the overall system complexity. The top-level scheme design and complexity evaluation presented in this study may provide technical support for the development of ECLSS in future manned spaceflights. Full article
