The ground may be used as a heat source, a heat sink or as a heat storage medium by means of vertical ground heat exchangers. Over the years various analytical and numerical models of varying complexity have been developed and used as design and research tools to predict, among others, the heat transfer mechanism inside a borehole, the conductive heat(More)
Pigs are used for long-term biomedical experiments requiring repeated injections, infusions and collections of blood samples. Thus, it is necessary for vascular catheters to be indwelling to avoid undue stress to the animals and the use of restraints. We propose a refined model of percutaneous insertion of long-term central venous catheters to minimize the(More)
