The phrase "a function of soot" is correct and usable in written English.
It can be used in contexts discussing the role or effect of soot in a particular process or phenomenon, often in scientific or technical writing.
Example: "The study aimed to determine the function of soot in the formation of urban smog."
Alternatives: "a role of soot" or "an effect of soot".
A specific pilot plant, based on a conical fluidised bed of glass beads, used to disperse fixed parcels of Diesel soot into a given gas flow rate, was used to assess the pressure drop and the filtration efficiency of the foam traps as a function of the soot particle size, the soot load in the filter, as well as the superficial velocity.
The smoke layer interface height as a function of time and soot mass fraction and temperature as a function of height have been registered during the simulation.
The results show that GDI soot contains an order of magnitude higher ash fraction than does conventional diesel soot, and oxidation reactivity is significantly enhanced by the catalytic effects of ash, as a function of ash content in soot.
Linear extrapolation of the maximum soot formation rates as a function of ambient temperature reveals a soot onset temperature near 1450 K.
Spectral soot emission was used to measure radially resolved soot volume fraction and soot temperature as a function of pressure.
The morphology and nanostructure of soot particles as a function of fuel type in a laminar diffusion flame were studied.
Figure 9 (sections c and d) shows the soot conversion values as a function of the temperature achieved for the catalysts (in "tight" soot-catalyst contact) along with Printex-U (no catalyst).
The soot volume fractions and temperatures were measured by spectral soot emission as a function of pressure for nitrogen-diluted n-heptane flames at 2, 5 and 7 atm.
A detailed soot model is included which can predict soot volume fractions as a function of the strain rate and the fuel mole fraction.
From the soot concentration distribution, soot yields were calculated as a function of flame height and pressure.
