Dispersion and partitioning in short coated tubes

The interaction of convection, diffusion, and interphase transfer is studied for a coated tube, with the fluid in the lumen in laminar flow. A solution is found directly in the time domain by series expansion, and computational results are presented for a range of parameter values and time scales to show the evolution toward classical chromatographic behavior at long times, where results are in agreement with those obtainable from the method of moments
