KFS MODELLING TECHNIQUES (page 1 - 2 - 3 )
KFS physical modelling techniques include:

aerodynamic  – water/bead modelling provides visual interpretation of flow patterns in kiln hoods, coolers and ducting (as shown on right)

combustion – acid/alkali modelling is used to demonstrate the efficiency of fuel and air mixing and define combustion zone length in a wide variety of processes (as shown in previous screen)
isothermal – uses miniature pitot tube measurements to determine exact flow velocities in different areas of the process

These are combined with KFS proprietary mathematical modelling software to analyse heat flux profiles and flame lengths.
