The approximate nonreflecting far-field boundary condition, as proposed by Engquist and Majda, is implemented in the computer code LTRAN2. This code solves the implicit finile-difference representation of the small-disturbance equations for unsteady transonic flows about airfoils. The nonrefiecting boundary condition and the description of the algorithm for implementing these conditions in LTRAN2 are discussed. Various cases are computed and compared with results from the older, moredoi:10.2514/6.1980-1393 fatcat:csobl5h5ovbitouxs6n3er4pwu
