The phenomenon of injection into a parallel slot under laminar flow condition is investigated analytically and numerically in this study. A comprehensive mathematical model capable of simulating the injection phenomenon from the initial stage until late stage is developed. It is shown that a tank model is necessary in order to reproduce the initial stage characteristic of the penetration in the slot. Numerical model with higher scheme is used to validate the mathematical model. The model is extended to model an experiment setup where injection in a cylindrical pipe under constant pressure was carried out. It is shown that the mathematical model is capable of reproducing the flow characteristics and thus justifies the need to include a tank model to comprehensively model the injection or grouting phenomenon.
