where 𝑚𝑝mp is the particle mass, 𝑈𝑝Up is the particle velocity, 𝐹𝑑Fd is the drag force, 𝐹𝑔Fg is the gravitational force, and 𝐹𝑠Fs is the particle lifting force. The drag force 𝐹𝑑Fd can be written in terms of the drag coefficient, 𝐶𝐷CD, as follows...
Integrated DAC systems have also been studied to supply climate-neutral CO2 for chemical processes (power-to-gas (PtG), power-to-liquid (PtL) and power-to-chemical (PtC)), closing the carbon cycle in the short term (direct air carbon capture and utilization—DACCU) [7,13,14,15]. ...
