Circular flow

This paper describes an investigation of fluid flow through two tandem circular cylinders using Lattice-Boltzmann Method in direct numerical simulation. The diameter ratio of two circular cylinders, D1/D2 varies from 0.5 to 1.5, and spacing ratio (L/D2) varies from 1.5 to 10, whereas the Reynolds number of 100 is considered. The numerical model is well validated by comparing the results with those obtained in the literature.

In this study, we developed a fluid flow solver based on the Lattice Boltzmann method to resolve those difficulties. Validation of the solver is performed through two flow problems, including impulsively started flow past a single circular cylinder at Re=3000 and pitching airfoil with large amplitudes and frequencies. The obtained results are in good agreement with the experimental and computational results listed in the references.

Ebook "Vortex, molecular spin and nanovorticity: An introduction" is the physics of vortices. A detailed analysis of the dynamics of vortices will be presented. The important topics of vorticity and molecular spin will be dealt with, including the electromagnetic analogy and quantization in superfluids. The effect of molecular spin on the dynamics of molecular nano-confined fluids using the extended Navier-Stokes equations will also be covered especially important to the theory and applicability of nanofluidics and associated devices.

This paper, the author built “Diagram of circular flow natural system” and combined with “Diagram of circular flow economic system”. The combination of these two diagrams generates an innovative circular flow between natural and economic systems. It is called “Diagram of circular flow economic and natural systems”. Different parts of this diagram represent an integral system containing multiple indicators measured in monetary values.

Lecture Chapter 2: Thinking Like An Economist, In this chapter you will: As scientists, economists try to explain the world using models with appropriate assumptions. Two simple models are the Circular-Flow Diagram and the Production Possibilities Frontier. Microeconomics studies the behavior of consumers and firms, and their interactions in markets. Macroeconomics studies the economy as a whole. As policy advisers, economists offer advice on how to improve the world.

The main target of the current study is to deeply understand the effect of different geometrical configurations of the circular inlet on performances of GLCC by the experimental method for two phases flow (gas-liquid). Two different inlet configurations are constructed, namely: One circular inlet and two symmetric circular inlets. As a result, we propose the use of two symmetric circular inlets to enhance the separator efficiency because of their effects.
