Abstract
Dynamic modeling of a double-pipe heat exchanger has been the subject of current study. The basis of this study is the same velocity of vapor and liquid phases or in other words, homogeneous phase in the annulus part of exchanger. The model can predict the temperature and vapor quality along the axial pipe from pipe inlet up to a distance where steady state conditions achieved. The simulation would be conducted for two modes of co- and counter- flow in a one dimensional transient system. The physical properties of water were estimated from empirical correlation and saturated vapor table with cubic Spline interpolation. The exchanger model which is a set of ordinary differential equations (ODEs), ordinary differential equations and algebraic equations has been solved numerically. Modeling results have been investigated for different operating times and two modes of co- and counter-current.
