/*! @brief Modified Sugrue lift coefficient for deformable bubbly flow.
 *
 *         Uses a Weber-number-based correction (Wo) and void fraction
 *         damping to compute the lift force coefficient.
 *         The returned coefficient is always positive; sign handling is
 *         done by the operator (Portance_interfaciale_PolyMAC_MPFA).
