        abstract = {In this research paper, this study examines higher-dimensional Bianchi Type-I cosmological models with string fluids under the framework of general relativity. Although the original objective was to investigate these models within Lyra’s geometry, the available resources predominantly emphasize general relativistic approaches. By synthesizing two complementary investigations a locally rotationally symmetric Bianchi Type-I model with bulk viscosity and a massive string cosmological model in five dimensions we derive exact solutions, analyze key physical parameters, and discuss their dynamical evolution. The models consistently demonstrate a transition from an early decelerating, anisotropic Universe to a late accelerating, nearly isotropic one. Bulk viscosity is found to play a crucial role in damping initial anisotropies, while compactification of the extra dimension provides a natural explanation for higher-dimensional effects becoming unobservable at late times. The results satisfy standard energy conditions and remain in qualitative agreement with observational evidence, including supernovae and cosmic microwave background data. This synthesis highlights the relevance of higher-dimensional string cosmologies in explaining inflationary behavior and accelerated expansion, while also setting the stage for future investigations within Lyra’s geometry.},
