Impact of myristic acid on novel designed manifold assimilated with domestic solar water heater: An experimental approach

In this study, myristic acid as heat storage material was assimilated with a novel designed manifold of evacuated tube solar collector (EVTSC). The foremost advantage of this design is that the integration of myristic acid in the manifold does not affect the vacuum tube's strength and does not...
