Abstract
The use of residual heat can reduce the energy needs of manufacturing plants. Low temperature industrial wastewater (IRW) heat can be used in heating plants. IRW heat removal can be accomplished using a Thermal Energy Storage Device (TES), which uses Phase Transition Materials (PCM). Wastewater The analysis is carried out by CFDs in the ANSYS CFX software. The heat absorption capacity and the IRW temperature difference are determined using paraffin Nano-fluid and alumina. The modelling represents the alumina Nano-fluid has a higher thermal capacity than paraffin wax, which is very useful for pharmaceutical systems that use industrial waste water for heating in the workshop. Temperature curves for different timings for paraffin and alumina based Nano-fluids were constructed using ANSYS CFX and temperature profiles were evaluated. Heat absorption in PCM is reduced when the material comes out of the industrial discharge pipe. Industrial wastewater loses maximum heat in the aluminium oxide water Nano-fluid, which is obtained in the form of a drop in temperature from 343 K to 324 K.
