Numerical Simulation Research on Flow and Heat Transfer Process of Fuel Nozzle

摘要

This article presents an investigation on the flow and heat transfer process of a gas turbine fuel nozzle with double channel. The fuel which is influenced by low flow velocity and high-temperature air around nozzle has high probability of coke deposition. The coke deposition problem is related with fuel temperature which is determined by flow and heat transfer process. A three-dimensional fluid-thermal-solid interaction numerical simulation solution is applied to acquire the temperature distribution characteristic in fuel nozzle. The numerical simulation result shows that the flow parameters of both air and flue have influence on the temperature distribution characteristic in fuel nozzle.
