Implication

Experimental and simulation study demonstrates enhanced thermal performance in plate heat exchangers using graphene oxide nanofluids, indicating viable efficiency gains despite pumping penalties.

Key Points

Assess the thermal and hydraulic performance of a compact plate heat exchanger operating with graphene oxide/water nanofluids across multiple concentrations and flow rates.
Synthesized and characterized graphene oxide nanoparticles using scanning electron microscopy, X-ray diffraction, and zeta potential stability testing.
Tested a 60° chevron angle plate heat exchanger experimentally with hot distilled water and cold nanofluid across varying volume concentrations.
Conducted three-dimensional computational fluid dynamics simulations matching the experimental plate geometry to evaluate temperature, pressure, and flow fields.
Nanofluid coolant increased thermal conductivity by ~13%, heat transfer rate by ~14%, thermal effectiveness by ~9%, and overall heat transfer coefficient by ~10%.
Thermal performance improvements came at the cost of higher pressure drops and elevated pumping power demands across the exchanger plates.
Exergy destruction reached a minimum at an optimal concentration of 1 Vol.% nanofluid, showing close agreement between numerical and experimental results.
