Popis:	Pressure fluctuations measured during slow drainage in a two-dimensional porous model exhibit sudden jumps that identify bursts where the invasion front proceeds abruptly. The pressure jump size distribution is observed to be exponential. The nonscaling dynamics created fractal fronts and invaded regions described by invasion percolation. A new modified invasion percolation algorithm includes invasion dynamics. A capacitive volume associated with each interface throat results in a crossover from power-law behavior to an exponential pressure jump distribution consistent with observations
