    The common working fluid in a heat exchanger can be identified as oil, water and ethylene glycerol. These fluids exhibit advantages in terms of ease of handling, recycling and disposing. Besides that, it has a low market price. Despite the advantages listed, these fluids are exhibits low thermal properties. Moreover, characteristic such as fouling and low total surface energy makes the overall heat transfer performance low resulting in the design of heat exchanger to be larger so that desired energy can be harnessed for the operations in the time duration. Nanofluid has been identified as a substitute to water and oil as a working fluid in the heat exchanger. There were attempts done to incorporate it into the industry. Graphene based nanofluid is found to be having significant thermal conductivity increase compared to other nanofluid. Thus, this study focuses on the acid treated GNP that has a better dispersion to flow in circular and square tube. The heat transfer ability of both the scenario is measured by the average heat transfer coefficient and Nusselt Number

    Modeling and analyzing the solid waste incineration process is a salient study for future advanced waste disposal technology and optimizing process efficiency. However, the development of a mechanistic model that describes the process deal with several challenges and has yet to be extensively explored. Thus, this paper aims to develop a mechanistic model for clinical and municipal solid waste incineration in Aspen Plus. The waste was modeled using customized non-conventional (NC) solid properties, and a general coal enthalpy model with heat correlations to calculate the heating value. The model results accurately depict the waste heating values found in the literature. Further analysis reveals the ability of the model to describe the effect of waste feed quality on incinerator performance

    It is a combination of banana leaf and starch powder designed as a wrap plate that is capable of sustaining the taste and heat of the food and ensure that the food wrapped lasts longer with great banana leaf fragrance.There are several alternatives available when looking for eco-friendly food containers. Banana leaf has become the “green gold” of today’s world because it has many beneficial qualities when compared to harmful and wasteful materials such as plastic.It’s time to wake up to the green alternative that really is a planet saver, banana leaf.Banana Leaf is a highly renewable, natural material that has antibacterial, antifungal properties and is biodegradable as opposed to plastic. This pack is precise size and light in weight and able to maintain heat the food for up to 30 minutes. Banana Leaf Pack is a very eco -friendly packaging good for ensuring the freshness and durability of food as well as affordability. This pack is fully-made up of organic materials that will never be a waste product instead will decay which could be used as a fertilizer in the future. This provides an alternative way to reduce the usage of chemical fertilizers. Organic matter is a material that people use in gardens because of its carbon-based compounds. Moreover, banana leaves contain large amounts of polyphenols which are known as natural antioxidants.These antioxidant can be mostly found in plant-based foods. Banana leaves absorb the polyphenols which are said to prevent many lifestyle diseases and kill germs in food
