Although the present classical second-order total variation diminishing (TVD) limiters with a wide application can well satisfy the computing requirements, its performance not only largely differs but also cannot be properly weighted between resolution and dissipation. Therefore, a new third-order TVD interpolation limiter (T-3 limiter) has been studied and compared with three classical limiters. First, through one-dimensional Riemann problem, it has been found that T-3 limiter is simultaneously characterized by both high intermittent resolution and excellent stability; then, by numerical simulation of hypersonic flow over a double-cone body and X-33 configuration, it has been found that T-3 limiter boasts the capability of portraying complex flow and good aerothermodynamic calculation performance. %K 限制器 %K 计算流体力学(CFD) %K 激波 %K 双锥绕流 %K 气动热< %K br> %K limiter %K computational fluid dynamics (CFD) %K shocks %K double-cone disturbance flow %K aerothermodynamic %U http://bhxb.buaa.edu.cn/CN/abstract/abstract14098.shtml
