Boiling of a pure fluid inside the rotor-stator cavities of a stator-rotor-stator spinning disc reactor (srs-SDR) is studied, as a function of rotational velocity x, average temperature driving force Delta T and mass flow rate phi(m). The average boiling heat transfer coefficient h(b) increases a factor 3 by increasing x up to 105 rad s(-1), independently of Delta T and phi(m). The performance of the srs-SDR, in terms of h(b) vs. specific energy input epsilon, is similar to tubular boiling, where pressure drop provides the energy input. The srs-SDR enables operation at epsilon > 10(5) Wm(R)(-3), yielding values of h(b) not practically obtainable in passive evaporators, due to prohibitively high pressure drops required. Since h(b) is increased independently of the superficial vapor velocity, h(b) is not a function of phi(m) and the local vapor fraction. Therefore, the srs-SDR enables a higher degree of control and flexibility of the boiling process, compared to passive flow boiling.
