We study holographic RG flow solutions within four-dimensional gauged supergravity obtained from type IIA and IIB string theories compactified on
orbifold with gauge, geometric and non-geometric fluxes. In type IIB non-geometric compactifications, the resulting gauged supergravity has
gauge group and admits an
vacuum dual to an
superconformal field theory (SCFT) in three dimensions. We study various supersymmetric RG flows from this
SCFT to
and
non-conformal field theories in the IR. The flows preserving
supersymmetry are driven by relevant operators of dimensions
or alternatively by one of these relevant operators, dual to the dilaton, and irrelevant operators of dimensions
while the
flows in addition involve marginal deformations. Most of the flows can be obtained analytically. We also give examples of supersymmetric Janus solutions preserving
and
supersymmetries. These solutions should describe two-dimensional conformal defects within the dual
SCFT. Geometric compactifications of type IIA theory give rise to
gauged supergravity with
gauge group. In this case, the resulting gauged supergravity admits an
vacuum. We also numerically study possible
RG flows to non-conformal field theories in this case.
