Abstract
Two-dimensional (2D) and axisymmetric minimum length nozzles (MLNs) with constant and variable specific heat were strictly designed using the method of characteristics (MOCs). MOC is a numerical technique which has great advantages in accuracy and efficiency for solving hyperbolic partial differential equations. According to previous MLN designs, violent vibrations of upper wall discrete points at the inlet were observed for 2D nozzles. Meanwhile, slight compressions could be observed in the flow field of axisymmetric nozzles designed by those methods. We proposed a novel technique in which the inlet grid is intensified to overcome the limitations mentioned above. Inviscid numerical simulations by CFD revealed that the proposed nozzle could meet the requirements for exit Mach number and flow field uniformity. Additionally, asymmetric MLNs could be used to hypersonic vehicles. The preliminary performances of 2D asymmetric nozzle with constant specific heat were investigated.
