This investigation is an extension of a previous publication [1] of pressure oscillations induced by forced convective heating of dense hydrogen. Among the pressure oscillations reported in that investigation were some which had the characteristics of Helmholtz modes and the harmonics of a pipe open at both ends. These oscillations are described as thermal-acoustic modes because their frequencies can be referred to acoustic frequencies. They can occur at sub and supercritical pressures, and in single and multiple channels. They only appeared when hydrogen entered a horizontal heated test section at a temperature below the saturated liquid temperature at subcritical pressures or below the temperatures at which specific heat is a maximum at supercritical pressures. Hydrogen in these states is referred to as dense hydrogen. Another experimentally determined condition for the appearance of thermal-acoustic oscillations was an intense heat flux during film boiling of the dense hydrogen. Consequently, the flow was usually gaseous along 80 to 90% of the length of the test section used in this investigation.
