How fired heater CFD handles flame shape, radiation and the process side of the tube: EDC and mixture-fraction models and their documented limits, discrete-ordinates radiation, NOx uncertainty, hydrogen in the fuel gas, the FEA hand-off for creep, and where surrogates help without replacing a plant test.
How chemical reactor CFD separates mixing from kinetics: Damkohler thinking, micromixing closures and the Villermaux-Dushman test reaction, exothermic hot spots and parametric sensitivity, reduced kinetics and neural closures with a stated range, coupling to process-simulator data, and where surrogates help.
How bubble column CFD handles hold-up and flow regimes, drag, lift and wall closures, population balance for bubble size, interfacial area and kLa with reaction, scale-up from pilot to plant, and where interface-resolving checks and AI surrogates help without replacing pilot data.
Fluidized bed CFD compared: two-fluid, MP-PIC and CFD-DEM, what the drag law and the mesh change, immersed tubes and erosion, why a bench cell misleads scale-up, and where AI closures and surrogates help without replacing pilot data.
How spray dryer CFD handles the atomiser spray, droplet evaporation and drying kinetics, turbulent gas-droplet coupling, sticky powder and wall deposition, cyclone losses and the outlet energy balance, what validation exists, and where surrogates help without replacing pilot trials.
How filtration CFD handles a filter housing: flow split across parallel cartridges, pleated media as a porous zone, cake growth from resolved particle runs, the pressure-drop sawtooth and what cleaning restores, erosion in solid separators, and where surrogates help layout studies.
How stirred tank CFD handles power draw, blend time, dead zones and shear: MRF, sliding mesh and large-eddy simulation compared, why scale-up criteria fail, how agitator loads reach FEA, and where surrogates over impeller diameter, speed and clearance help without replacing a tracer test.
