Abstract


The research work is focused on the residence time distribution (RTD) studies in small pipes using pulse input technique. The extent of dispersion is expressed in terms of dispersion coefficient (DL). RTD studies are carried out by tracer analysis and DL is estimated using axial dispersion model. Laminar flow in short pipes follow pure convection model but the experimental data in the present study is found to be in good agreement with axial dispersion model. The variance and dispersion coefficients are estimated and the effects of flow and geometric parameter on dispersion coefficients are studied. In scope of present study, the dispersion coefficient is found to increase with an increase in velocity and length of tube but the effect of pipe diameter on dispersion coefficient is found to be marginal.
