Multiphase thermal platforms (involving a couple of part or one part) have a number of purposes in aerospace, heat-exchanger, shipping of contaminants in environmental platforms, and effort delivery and effort conversion structures. Advances in realizing the behaviour of multiphase thermal structures may lead to raised potency strength creation platforms, stronger heat-exchanger layout, and more secure and stronger therapy of dangerous waste. yet such advances were drastically hindered by way of the powerful impact of gravitational acceleration at the stream. looking on the move orientation and the part velocities, gravitational forces may well considerably modify the stream regime, and for that reason the pressure-drop and heat-transfer coefficients linked to the movement. a discounted gravity atmosphere (or ""microgravity""), presents an outstanding device to check the move with out the covering results of gravity. This e-book offers for the 1st time a accomplished assurance of all elements of two-phase circulation behaviour within the digital absence of gravity.

MODELING AT REDUCED GRAVITY Dukler et al. (1988) reported a set of experimental data with models to predict flow pattern transitions at microgravity. They classified gas–liquid flow into three flow patterns: bubble, slug, and annular.

An outer cylinder – made of brass, tapped for two BNC connectors – was positioned over the electrodes. The outer cylinder, running the full length of the sensor, acts as a guard and was electrically in contact to the shield electrode. The shield electrode was grounded to the guard electrode to eliminate electric field lines running along the wall of the tube. Thus, the void fraction measurement is based on a measurement due to the electric field lines running across the tube diameter rather along the tube wall.

A variety of electrode configurations have been designed by a number of researchers; ranging from flat plate, concave, helical, and multiple helical wound, where the electrodes were either in contact or isolated from the fluid. Two capacitance sensors were used by Geraets and Borst (1988), where one tube had an inside diameter of 50 mm and the other was 5 mm. The sensors used by them were of the helical wound type having 2 thin brass strips wound around a thin acrylic tube. The brass strips were placed such that they are always opposite to each other.
