“…HC emissions from hexanol and biodiesel blends were lower than diesel at all loads. This attributed to the excess oxygen present in the fuel (Yuvarajan and Venkata Ramanan 2016a). HC emissions increased with load for all the fuels.…”

In this study, the effect of doping hexanol into biodiesel which is from neat cashew nut shell biodiesel oil on the emissions and the performance characteristics was studied in a constant speed diesel engine. The main purpose of this work is to reduce various emissions and also to improve the performance of the diesel engine when fueled with blends of hexanol and neat cashew nut shell biodiesel. Cashew nut shell oil is not edible, and hence it can be used as a viable alternative to diesel. Cashew nut shell biodiesel is prepared by conventional transesterification. Hexanol with 99.2% purity was employed as an oxygenated additive. Experimental studies were conducted by fueling diesel as a baseline and by fueling hexanol and neat cashew nut shell biodiesel mixture. A fuel comprising 10% (by volume) of hexanol and 90% (by volume) neat cashew nut shell biodiesel was referred to as CNSBD900H100 and fuel comprising 20% (by volume) of hexanol and 80% (by volume) of neat cashew nut shell biodiesel was referred to as CNSBD800H200. This study also investigated the possibility of using pure biofuel in an unmodified naturally aspirated diesel engine. The outcome of this study showed that adding hexanol at 10% and 20% (by volume) to cashew nut shell biodiesel results in a reduction in emissions. In addition, a significant improvement in brake thermal efficiency and reduction in brake-specific fuel consumptions were achieved. Hence, it could be concluded that hexanol could be a viable and promising additive for improving the drawbacks of biodiesel when it was used to fuel an unmodified diesel engine.

“…It is illustrated how the Russian paradigm of problem‐solving, TRIZ, can be tweaked to shed light on and control this transfer process. Furthermore, life makes use of software and structure, two facets that technology typically disregards, whereas technology largely modulates the use of energy to resolve things (Devarajan & Venkata Ramanan, 2016; Ricatti et al., 2019).…”

Multiple ecological tactics, like the ones described here, can be imitated to strongly affect these two components in the construction sector. This article provides an in-depth examination of the literature on biomimicry-based strategies intended to enhance building designs. This analysis is motivated by the rising need for energy legislation to achieve future local goals and provide a framework for use in Panama.These biomimicry-based methods have undergone more review and evaluation, and the incorporation of organism-based design for three of Panama's climate types has been proposed. Therefore, a SWOT analysis assisted in realizing the full potential that biomimicry-based techniques might have in raising the likelihood of satisfying local and international regulatory standards. In order to design constructions using biomimicry, multidisciplinary collaboration is required. This gives a competitive edge for better-trained human resources and expands horizons in the conventional construction industry. Finally, the analysis provided here might act as the preliminary step for the additional technical assessment using numerical and experimental procedures.

“…Raeisian et al (2019) investigated the possibility of using waste vegetable oil as a suitable replacement to the cooling fluid in high voltage transformer and finds out that both the dielectric and thermophysical properties of waste vegetable ester were better than that of the mineral oil and concluded that the vegetable oil is a better replacement to the commercially available mineral oil. Yuvarajan et al (2016), produced methyl ester from rice bran oil and observed the effect of adding magnetite nanoparticles. They observed a 2 o C increase in flash point with the addition of magnetite.…”

In recent times, due to environmentally friendly issues, sustainable resources, and higher concerns regarding safety, research in the area of alternative liquid insulation in high voltage apparatus has been necessary. To actualize this goal, vegetable oil has been studied extensively and it has the potential to replace mineral oil in power transformers. In addition, the incorporation of nanoparticles has been remarkable in producing improved characteristics of insulating oil. In this study optimization of the Thermophysical properties which include viscosity, and the flash point was done using the Taguchi approach of design of experiment. The concentration of the nanoparticles, mixing, and drying time were varied and an optimal combination of parameters was observed and recorded. The optimum parameter combination for flash point is 0.9wt% concentration, 45 minutes mixing time, and 3hrs drying time. Viscosity has its optimum parameter combination at zero concentration of nanoparticles, mixing, and drying time. The optimized values of the thermophysical properties of the nanofluid reveal that the natural ester-based nanofluid is a suitable replacement for mineral oil in transformer cooling and insulation because of its improved properties. A mathematical model for the combination of concentration of nanoparticles, mixing and drying time for viscosity and flash point was developed and statistically validated. Hence can be used to navigate and predict the viscosity and flash point of the nanofluid within and outside the experimental design space.
