 many applications in industry and in nature\, particle or droplet transpor
 t in turbulent flow plays a role. Examples are combustion of fuel particle
 s (biomass or metal) and cloud formation. In our group we study methods an
 d models for accurate simulations of particle-and droplet-laden turbulent 
 flow.  For particle-laden homogeneous isotropic turbulence it is usually a
 ssumed that particle collisions are not important if the particle volume f
 raction is less than 10-3. In  inhomogeneous turbulent flow much higher pa
 rticle volume fractions can occur locally due to turbophoresis and particl
 e clustering. We investigated the effects of particle collisions for this 
 flow and studied the particle collision rate in order to enable stochastic
  collision modeling.  For particles larger than the smallest scale of turb
 ulence\, point-particle methods are inaccurate due to the use of correlati
 ons for the drag force which only hold if particles are sufficiently small
 . A way to improve these correlations is by particle-resolved DNS. We used
  this method in turbulent flow in a channel with an array of particles to 
 determine optimal values for the coefficients in a correlation for the dra
 g force. The use of this optimal correlation in point-particle DNS results
  in better agreement with the results for the particle-resolved simulation
 .
