Abstract A global method of generalized differential quadrature is applied to solve the two‐dimensional incompressible Navier‐Stokes equations in vorticity‐stream‐function formulation. Numerical results for flow past a circular cylinder were obtained using just few grid points. good agreement found with experimental data.
Considering the fact that compression work done by pressure and viscous heat dissipation can be neglected for incompressible flow, its relationship with gradient term in evolution equation temperature thermal energy distribution model, a simplified model is proposed. This does not have any much easier to implemented. validated numerical simulation of natural convection square cavity at wide range Rayleigh numbers. Numerical experiments showed keep same order accuracy as but it requires less...
In this paper, a data driven approach is presented for the prediction of incompressible laminar steady flow field over airfoils based on combination deep Convolutional Neural Network (CNN) and Multilayer Perceptron (MLP). The an airfoil depends geometry, Reynolds number, angle attack. conventional approaches, Navier-Stokes (NS) equations are solved computational mesh with corresponding boundary conditions to obtain solutions, which time consuming task. present approach, approximated as...
Abstract Recently, great progress has been achieved in the design and preparation of conjugated organic polymer photocatalysts for hydrogen generation. However, it is still challenging to develop an photocatalyst with high photoconversion efficiency. Rational structure holds key point realize photocatalytic performance. Herein, a series donor–π–acceptor (D–π–A) copolymer developed using statistical copolymerization by tuning feed molar ratio pyrene (donor) dibenzothiophene‐S,S‐dioxide...
This paper proposes an approach to perform the inverse design of airfoils using deep convolutional neural networks (CNNs). The conventional approaches are based on solution differential equations, which either difficult solve or take a tedious procedure obtain solution. As shown in this paper, learning technique can be used effectively airfoil shape from coefficient pressure distribution. More specifically, CNN is applied due its ability handle any geometry without need for complex...
Abstract The solar‐driven photocatalytic production of hydrogen peroxide (H 2 O ) from water and oxygen using semiconductor catalysts offers a promising approach for converting solar energy into storable chemical energy. However, the efficiency H is often restricted by low photo‐generated charge separation, slow surface reactions inadequate stability. Here, we developed mixed‐linker strategy to build donor‐acceptor‐acceptor (D–A–A) type covalent organic framework (COF) photocatalyst,...
Microflow has become a popular field of interest due to the advent microelectromechanical systems. In this work, lattice Boltzmann method, particle-based approach, is applied simulate two-dimensional isothermal pressure driven microchannel flow. Two boundary treatment schemes are incorporated investigate their impacts entire flow field. We pay particular attention and slip velocity distributions along channel in our simulation. also look at mass rate which constant throughout overall average...
We report two chaotic micromixers that exhibit fast mixing at low Reynolds numbers in this paper. Passive mixers usually use the channel geometry to stir fluids, and many previously reported designs rely on inertial effects which are only available moderate Re. In paper, we propose using two-layer crossing channels. Both numerical experimental studies show very efficient for fluid manipulation numbers, such as stretching splitting, folding recombination, through advection can be generated is...

For each configuration, various geometrical arrangements are considered, order reveal different regimes characterized by gap between cylinders. work, simulations carried out low Reynolds number range, that is, Re =100 200.
