Abstract: | A theoretical model of fewturn heat pipes is suggested. The equation for boiling liquid flow in a capillary of the pipe, which allows for the pressure difference of saturated vapor and for gravity and viscosity forces, is written. The parameters at which selfoscillations of the liquid occur have been estimated. It is shown that the period of selfoscillations is determined by the characteristic time of heat exchange between the liquid in the capillary and the surrounding medium. The time of selfoscillations obtained theoretically is in good agreement with the experimental one. |
