We present a reduced order dynamic predictive model for direct contact membrane distillation process. ? Both time varying and steady-state responses are well captured and have been validated with experimental data. ? Analysis shows the response of several intrinsic variables under various conditions. ARTICLE INFO Article history: Received 24 March 2016 Received in revised form 18 August 2016 Accepted 5 September 2016 Available online 2 October 2016 Keywords: Dynamic modeling Direct contact membrane distillation (DCMD) Spacial temperature distribution Electrical analogy Heat and mass transfer Flux predictions Time response ABSTRACT Membrane distillation (MD) is an emerging technology that has a great potential for sustainable water desalination. In order to pave the way for successful commercialization of MD-based water desalination techniques, adequate and accurate dynamical models of the process are essential. This paper presents the predictive capabilities of a lumped-parameter dynamic model for direct contact membrane distillation (DCMD) and discusses the results under wide range of steady-state and dynamic conditions. Unlike previous studies, the proposed model captures the time response of the spacial temperature distribution along the ?ow direction. It also directly solves for
