“The aim of this thesis is to study the thermal signature produced by a squirt of heated waterjet for humanitarian demining. Thermal simulation of the process was developed using I-DEAS and FLUENT. In the experiments, the thermal signature generated from a single squirt of a heated water jet was investigated. A heated waterjet, as it penetrates the ground, digs a hole through which the heat radiates out. The possibility of using the thermal profile induced by a heated waterjet when viewed directly into the hole created by the waterjet to define mine location was explored. The thermal profile was taken viewing directly in the hole.

I-DEAS was used to simulate the heat transfer and radiation phenomena associated with demining related problems. First, a mine buried in sand and the high temperature cone shaped hole on top the mine produced by the squirt was studied. Second, the radiation difference for different lengths of hole was studied. Third, the heat radiate to the IR camera from a hole on top a mine created by the waterjet was simulated. In the simulation, the mine is assigned the properties of metal and wood, respectively. From the metal and wood mine calculation results, some of the experimental results were verified.

FLUENT was used to simulate a stream of high speed waterjet hitting the ground. From pressure and velocity distribution calculation, when water impinges on the ground, it will produce a cone shaped pressure zone which is the reason for the formation of a cone shaped hole on top of the mine”--Abstract, page iii.
