Experimental Investigation on Heat Transfer Enhancement in Shell and Tube Heat Exchanger Using Graphene Nanofluids
Abstract: The paper focuses on the dispersion of Graphene nanoparticles in a water–ethylene glycol based fluid to investigate their impact on the convective heat transfer performance of the resulting nanofluid. Various concentrations of graphene nanoparticles were prepared, and the nanofluids were subjected to different ultrasonication durations to ensure proper dispersion and stability of the nanoparticles within the base fluid. The study involved extensive experimental evaluation to systematically analyze how the nanoparticle …

Advancements in Waste Heat Recovery from Multistage Air Compressor Operations
Abstract: In industrial production processes, waste heat is an important consequence, especially in sectors that rely significantly on composites and polymers. Frequently, this heat is released into the atmosphere without being captured, which raises operating expenses in addition to wasting potential energy. In these sectors, waste heat recovery, or WHR, has become a key tactic for raising sustainability and energy efficiency. The WHR potential of multistage air compressors—essential parts of industrial …
