CFD Flow Analysis
Alongside its filter bag manufacturing, Micro-one Co., Ltd. designs and builds waste incinerators, flue gas treatment systems and power plant dust collection equipment on an EPC basis. Designs are checked with CFD flow analysis and 3D modeling, and every system can be fitted with Micro-one’s own DuraFill™ and CataFill™ filter bags.
We offer cost-effective consulting tailored to each customer and provide after-sales service once the plant is handed over.

Computational fluid dynamics (CFD) simulates gas flow, temperature and particle movement on a computer so engineers can see inside equipment before it is built. For dust collectors and reactors, it shows at the design stage whether the gas is evenly distributed, whether reagents and sorbents mix well, and where dust will settle. Micro-one applies CFD to equipment design, drawing on its experience designing and building dust collection and air pollution control systems.
Define the type of fluid to be analyzed, flow conditions (velocity, pressure, temperature, etc.), and boundary conditions (wall surfaces, inlet/outlet conditions)
(e.g., gas distribution in a dust collector, sorbent mixing in a reactor, duct pressure drop)
Create a 2D or 3D model of the equipment using CAD software or existing design data
Divide the computational domain into small cells to create a computational mesh. Mesh size and shape influence calculation accuracy and time
Enter the fluid’s physical properties (viscosity, density, thermal conductivity, etc.), define initial and boundary conditions, and select turbulence, heat transfer and chemical reaction models
Run the calculations in CFD software (e.g., ANSYS Fluent, OpenFOAM), solving the governing equations iteratively until the solution converges
Visualize results for velocity, pressure, temperature, turbulence intensity, and particle trajectories. Use graphs, contour plots, and animations to analyze flow patterns
Reduces cost and time by minimizing physical testing and simulating conditions that are hard to reproduce in experiments
Shows detailed flow behavior, including regions that cannot be measured in experiments
Can model various physical phenomena such as heat transfer, chemical reactions, and aerodynamics
Design changes can be tested in simulation to improve performance before anything is built
Boiler combustion, turbine heat transfer and flue gas flow analysis
Flow inside dust collectors and reactors, air pollutant dispersion simulation
Fluid flow in reactors, optimization of mixing and separation processes
If the gas flow is uneven, some filter bags wear out early, the pressure drop rises and efficiency falls. CFD lets designers position distribution plates and guide vanes in advance so the gas is evenly distributed.
In waste incinerator design and in the hood and duct design of tripper room and storage dust control systems.
