Background physics

The physics behind GUNDALF is based originally on Laws, Hatton and Haartsen, (1990), "Computer Modelling of Clustered Airguns", First Break, vol. 8, no. 9, (Sept.) which itself builds on earlier published contributions by Anton Ziolkowski, Svein Vaage, Gregg Parkes and Bill Dragoset supported by experimental work done by Tor Haugland, Mike Hall and others. The model solves a complex set of differential equations combining both heat transfer and dynamics.

Over the last 10 years, this has been incrementally refined with modifications to the physics by Les Hatton to handle the 'super-foam' region of colliding bubbles and also to handle innovations such as injector guns. Periodically over the years, the model has been calibrated against measurements of both non-interacting guns and interacting clusters. The model produces signatures within the experimental error of the measurements and accurately models the phase-locking of airgun clusters reported in the above paper.

The model is unconditionally stable for all airgun combinations no matter how close.
