Day By Day

Cooking has become a challenge in areas where the energy access is limited and the single available fuel is wood. Day by day, more people have been reported with respiratory diseases, caused mainly by the smoke that emits carbon monoxide (CO), particular matters (PM) and other highly harmful compounds resulting from the poor combustion generated on the simplest stoves those using fuel wood. Hence an efficient, hot burning Rocket Stove has been deployed with fabric filters in the earlier days. However, the rocket stoves with fabric filter removes the PM content that is also in small amount mean while considering CO, CO2 and other toxics remains same in the emitted gas/smoke. To tackle with these pollution issues, our proposed work innovates a Bi-folded Colander Framework, which combines a Knapsack filter and simulated Carbon with Cellulose Nano fiber filter to purify the exhaust gas/smoke. It is highly sensitive to filter the nano particles as well the toxic compounds exist in the exhaust smoke. Thus our proposed methodology effectively reduces the pollutions with our novel framework and enhances the fuel efficiency of the rocket stove.

Exhaust Energy

The exhaust energy recovery is significant for engine fuel efficiency. However, the exhaust gas interference and the loss of flow affect the utilization of exhaust energy of multi cylinder turbocharged diesel engine seriously. In this paper, through Particle Image Velocimetry experiment and computational fluid dynamics simulation of exhaust T-junction flow field, the characteristics of junction local flow field and the law of energy loss are obtained. Based on the one dimensional simulation of engine working process, the exhaust available energy analysis is carried out, and the transmission of available energy of exhaust valve and various pipe systems under typical operating conditions is obtained. On this basis, five exhaust systems are designed, and the steady-state and transient performances are compared by bench tests. The results show that the shrinkage rate and the intersection angle of T-junction are the key factors affecting exhaust energy transmission and exhaust gas interference suppression. Reducing the branch pipe shrinkage rate leads to an increase in branch pipe flow loss, but it will also reduce the main pipe flow loss and exhaust gas interference. Reducing the angle between the main pipe and branch pipe is beneficial to the exhaust flow and exhaust energy recovery. The pulse converter exhaust system has a high exhaust available energy transmission rate; the Modular Pulse Converter system has superior fuel efficiency and transient response performance from the perspective of the entire engine operation range. The 90% response time difference between the five studied exhaust systems is about 0.41 s.

Resin Matrix Composite

Polymer composite with reinforced fiber is a remarkable development in the field of engineering materials. The applications of composite materials have significantly increased in Defense, Aeronautical and Automobiles because of its specific modulus and high strength characteristics. In composite material development, nano particles reinforcement and nano fiber reinforcement are the most recent methods developed. In this research electrospun carbon nanofiber reinforced mat with polymer epoxy resin composites was prepared. X-ray diffraction, scanning electron microscope and ultrasonic scanning were used to study the morphology and the defect on the specimens for analyzing the structural conditions of the samples for determining the mechanical properties. The result clearly indicates that the Carbon Nanofiber (CNF)/ Polyvinyl Alcohol (PVA) mat improves the flexural strength of the epoxy resin and that 0.015% CNF in PVA gives a better mechanical strength.

Abstract Nowadays there are more interesting with nanotechnology and its applications in several sectors specially in medicine for diagnoses, therapeutic and research biomedical tools. It can be defined as any process or technique used to produce material in nano-scale structure with particle size ranged from 1-100 nm. The utilization of nanotechnology in human health benefits known as nano medicine. So that nanotechnology has firmly entered the drug delivery realm to maximize drug therapeutic activity and minimize its undesirable side effects. Herein we deal with both nanoparticles and nano-fibers and their applications in medical field. Nano-particles have unique properties from its small size with high surface area therefore it provides larger than particle numbers from that prepared with convention methods. In addition, nanoparticles can be used to improve various drug bio-availability from its biodegradability and bio-compatibility. Nano-fibers have huge surface area to volume ratio which increase its performance in several applications. Nano-fiber produced via electrospinning process (simple and have high production rate). It can be used in many applications such as water filtration, tissue engineering scaffold, wounds, fiber composites, drug release and protective clothes.
