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.
