Abstract: Due to the complexity of gas turbines and the increasing requirements (including economic,safety and environmental protection) being imposed upon,the pressure to decrease the design and development costs,time and risks of gas turbine is accordingly increasing.With in depth study of various physical phenomena,precise models of different parts and different disciplines have been developed.However,it is not an easy job to integrate these models into a system model.One particular difficulty comes from the fact that different hardware/software platforms and different programming models are used.In order to make these models interact,distributed simulation environment and unified programming model must be used.The programming models used in general distributed systems can be classified into message passing,control flow,data flow,blackboard/shared space, mobile object/agent.In this article,these programming models are generally described and their applications in gas turbine distributed simulation are also reviewed.However,one serious drawback of the programming models been used is that they lack direct support for distributed simulation,so the needed features have to be added usually at the will of the developers, without taking into consideration of standardization.The US Department of Defense has set down a distributed interactive simulation standard High Level Architecture,whose main purpose is to facilitate the reusability and interoperability of simulation.The HLA should also be adopted as the standard for gas turbine distributed simulation to facilitate the multi site,muliti part,and multi discipline integrated simulation of gas turbine.Some advice on further development of gas turbine simulation is also given to domestic researchers.
