Abstract : A number related problems concerning the utilization of unconventional effects for the purpose of affecting the behavior of fluids are investigated. Effects capable of directly converting thermal or electrical power into pumping power without the use of moving mechanical parts are studied. A means of improving the thermoelectric cooling of liquids is investigated. A way of decontaminating fluids by an electrical effect is studied. Finally, a scheme for suppressing pressure surges in flowing fluids is examined. The subject areas examined were as follows: thermal pumping, thermoelectric-hydromagnetic pumping, electrokinetic energy conversion, acoustic pumping, the winslow effect valve, electromagnetic induction pumping, the sumotoion motor, influence of a magnetic field on thermoelectric cooling, decontamination by dielectrophoresis, and attenuation of pressure surges by tapered pipes.
