•MB model is modified with relative velocities between boundaries and fluid.•MB model is developed in MATLAB language using discretized method.•Chattering is suppressed using proposed model.•Transient characteristics of a novel HYDROX system is obtained.
Moving Boundary (MB) dynamic model is an appealing approach for investigation of advanced control schemes for two-phase flow heat exchanger. For the confusion of relative velocities between boundaries and fluid existing in the previous MB model, this paper presents a modified moving boundary model. The dynamic model incorporated with the relative velocities is derived from physical principles of mass and energy conservation. And the model is then implemented in a novel underwater HYDROX system to predict cyclic performance. The simulation results from discretized model using MATLAB language show that the oscillations which is known as “Chattering” have been suppressed.
