A theoretical analysis of the dynamic behavior of pressure drop in long steam generating tubes is presented. The solutions of the dynamic response of the frictional pressure drop, the accelerational pressure drop and the gravitational pressure drop to changes of flow rate at the inlet of the tube and heat input are derived. The derivations are based on a long steam generating tube and heat input are derived. The derivations are based on a long steam generating tube with uniform heat flux and constant cross section and on the linearization of the fundamental equations. The characteristics of the response curves of the frictional pressure drop are discussed in detail. It is shown that the response curves to a step increase of the inlet mass flow rate show a special feature, for instance, the frictional pressure drop at first increase remarkably and then decreases gradually to a settling value which is lower than the initial value.
