In dispersed two-phase flow, experimental data indicate that the effective drag force on individual dispersed elements∗ is strongly influenced when the dispersed phase is present at high volume fractions. This appears to be true whether the DPEs are solid or fluid (i.e. droplets or bubbles). The paper first reviews the literature relating to the modelling of the drag force in densely dispersed ...

carbon disulfide is used predominantly in the manufacture. it has affects the nervous system. in this study, the applicability of spme as a passive sampler for determination of carbon disulphide in air was studied. effect of sampler and environmental parameters on uptake of carbon disulphide was studied as well. four fibers were tested to select the best sampler for determine carbon disulfide i...
