中文摘要：

为了对先进旋涡燃烧室（AVC）的流动和传热性能进行综合评价,对不同来流速度、来流温度、壁面温度下AVC燃烧性能进行了数值模拟,对速度场、温度场、压力场进行了多场协同分析。结果表明：随着燃烧室来流速度的增大,速度与速度梯度的协同角α、速度与温度梯度的协同角β,速度与压力梯度的协同角θ均减小,温度梯度与速度梯度的协同角γ及压力梯度与速度梯度的协同角φ增大。随着来流温度的提高,α,θ增大,β,γ,φ减小。随着壁面温度的提高,α,θ减小,β,γ,φ增大。对于AVC湍流流场的传热强化问题,增大来流速度和来流温度,降低壁面温度会强化流动换热;增大来流速度和壁面温度,降低来流温度可以减少传热功耗;增大来流速度和壁面温度,降低来流温度能够提高强化传热的综合性能。

英文摘要：

In order to evaluate the flow and heat transfer characteristics of Advanced Vortex Combustor（AVC） comprehensively,the variation of combustion characteristics in AVC with incoming velocity,incoming temperature and thermostatic wall temperature was numerically calculated. And an analysis of multi-field synergy on velocity field,temperature field and pressure field has been carried out. The results show that as the increase of the incoming velocity,the synergy angle α between velocity and velocity gradient,the synergy angle β between velocity and temperature gradient,the synergy angle θ between velocity and pressure gradient decrease,the synergy angle γ between temperature gradient and velocity gradient,the synergy angle φ between pressure gradient and velocity gradient increase. With the increase of the incoming temperature,α and θ increase,whileβ,γ and φ decrease. With the increase of the thermostatic wall temperature,α and θ decrease,while β,γ andφ increase. For turbulent flow field of heat transfer enhancement in AVC,increasing the incoming velocity and incoming temperature,reducing thermostatic wall temperature can enhance flow and heat transfer. Increasing the incoming velocity and thermostatic wall temperature,reducing incoming temperature can reduce the flow resistance. Increasing the incoming velocity and thermostatic wall temperature, reducing incoming temperature can raise the overall performance of heat transfer enhanced.
