This paper represents an endeavor to review the advancements achieved in the topic of coupled radiation-free convection (CRFC) across various investigated models. Through detailed bibliometric analysis, the paper not only underscores the importance of CRFC publications but also highlights their frequency, signaling an increasing interest and significant contributions in this domain. The literature review is systematically structured, categorizing studies based on the types of cavities/enclosures with or without internal heating sources, thereby providing a comprehensive and structured overview of this field. It then delves into the crux of CRFC, giving the governing equations, assumptions, parameters, and variables, establishing a robust knowledge. Transitioning seamlessly to application, the paper explores simulated models, boundary conditions, and insightful result discussions. Notably, the proven influence of surface thermal radiation in enhancing free convection heat transfer throughout the reviewed studies underscores CRFC's transformative potential, paving the path for innovative advancements in thermal engineering systems.
