Water impact investigations

This thesis investigates the SPH capability available in the commercial Finite Element (FE) code LS-DYNA®, for water impact problems. Experiments have been conducted on rigid wedges impacting water, which were then simulated with the SPH method. Although certain limitations were experienced with the experimental results, a positive correlation was observed with the numerical technique, thus establishing SPH as a promising method for crashworthiness design.

The aim of this research was to investigate the formation of hydrogen sulphide for different sewage characteristics and flow rates. An experimental set-up was developed to simulate a section of a gravity sewer pipe, the set-up comprised of a pipe of 2 m long and 155 mm inside diameter, referred to in this thesis as a laboratory sewer pipe. The first stage of the experimental program involved developing a biological growth rich in sulphate-reducing bacteria inside the laboratory sewer pipe using synthetic sewage.
