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.
