This experimental work analyzes the usage of 100% of Waste Plastic Oil (WPO) in low heat rejection (LHR) diesel engine without diesel. For this purpose, the hardware components of conventional diesel engine were coated with lanthana-doped partially stabilised zirconia, to a thickness about 300 μm by plasma spray coating technique. WPO was produced in a research facility scale setup by pyrolysis method. Coated and uncoated engines were tested with WPO and the outcomes were compared with diesel. Results authenticate the objective of this study and shows enhancement in performance and diminution in specific fuel utilization. The reduction in emission with exception of NO x was noticed in lanthana-doped partially stabilised zirconia coated engine than that of uncoated diesel engine.

In this work, a Gorlov helical type Vertical Axis Wind turbine (VAWT) model is designed and manufactured by using one of the additive manufacturing techniques called Fused Deposition Modelling (FDM) through a 3D Printer. The VAWT was made by interpretation of the wind conditions and by selecting of the suitable Airfoil profile for the blades of the turbine based on the DMS analysis (Q-Blade is an open source software which is particularly used in designing of wind turbine blades). The CAD modelling is done on SOLIDWORKS 2017 and later converted in to a Stereolithography (STL) format file which is compatible with the 3D Printing software called CURA by Ultimaker. All the parts were manufactured on the 3D Printer and assembled together and coupled with the suitable generator for the generation of Power. This VAWT is more suitable for urban areas and can generate more power even at the lower wind speeds unlike the Horizontal Axis Wind Turbines (HAWT) which require open lands for their efficient working.

Metal nitride multilayer films display a unique combination of exceptional properties with respect to optical absorption, thermal emission, corrosion resistance, adhesion between coating and surface and high temperature withstand. Most considerable aspects of nitride coatings were economical, environmentally friendly and easy to develop. Similar to nitride thin films, to achieve a considerable absorption (α)-0.92 and low emission (Є)-0.08 along with chemical and radiation stable solar selective coatings, Diamond Like Carbon (DLC) thin films exhibit the desirable properties for Concentrated Solar thermal Power(CSP)applications. The main advantages of DLC films were high hardness, chemical and radiation stability and good control over the optical properties. To achieve above-mentioned properties, optimization of each layer of the DLC coating has needed. The main aim of this research is optimization of Cr-base layer using Cr-Target current 175A to get 125 nm thicknesses, optimise the AlSiN absorber layer by controlling the AlSi-target current 175A to maintain 35nm thickness. The sequence of the DLC coating layers was selected based on their relative thickness, which was optimize to get good solar selectivity (α/Є). Individual layers of the DLC solar coatings have unique properties to get overall required high absorbance and low emission along with chemical and radiation stability. These solar selective multi-layers (Cr/DLC/AlSiN) have deposited by using available Cathodic targets (Cr , AlSi & Ti) in Cathodic Arc Physical Vapor Deposition (CAPVD) and optimized parameters were mainly depend on the target currents to control over the thickness of the each layer, base pressure 1*10-5 mbar and deposition temperature 400°C. The DLC multilayer solar selective coatings were characterized using Ultraviolet Visible Near infrared (UV-Vis-NIR) spectrophotometer, Scanning Electronic Microscopy (SEM), Transmission Electron Microscopy (TEM) and Raman spectroscopy etc. Scratch test and corrosion tests have conducted for these absorber coatings testing.
