Detailed Description

One propellant stream at the injector face. All SI.

``phase`` is ``"liquid"`` or ``"gas"`` **at injection conditions** and decides which lags apply
at all — it is not a cosmetic label. ``D0`` is the initial drop size from the injector's own
spray model (SMD), ``d_orifice`` is L17's liquid post inner diameter ``D_l``, and ``u_inj`` is
its injection velocity ``u_l``.
