Property of Transient Particle Number Emissions from Diesel Engines with Biodiesel Fuel for Mechanical Engineering

Particle number emissions from a light duty vehicle diesel engine during transient state operating conditions were studied. Test fuels were petroleum diesel, pure Jatropha biodiesel, B20 and B50 biodiesel blend fuels. The results show the number of nucleation mode particles from the engine increases when using petroleum diesel during the transient operating condition Increasing torque at constant speeds . The number of accumulation mode particles increases at the initial stage of the transient process and then descends with increasing torque. The total particle number increases continuously with torque during the transient operating condition, and accumulation mode particles play an important role in the beginning, and nucleation mode particles dominate the later part of the transient operating condition. Dynamic characteristics of particle number using lower biodiesel blend during the transient process is similar to that of petroleum diesel, whereas higher biodiesel blends show distinct differences, and the total particle number and nucleation mode particle number using B50 and pure biodiesel fuels are obviously larger than pure diesel from beginning to end, while the accumulation mode particle number keeps smaller. For the pure biodiesel fuel, the nucleation mode particle number rapidly ascends until the end of the transient process, and accumulation mode particle number continuously descends.

Static Structural Analysis of Vented and Non Vented Disc Brake

The current study essentially deals with the modeling and analyzing vented and non vented disc brake by CATIA and ANSYS. Finite element models of the brake disc are shaped with CATIA and simulated using ANSYS which is based on the finite element method. This study Structural analysis is done so as to get the strength of the disc brake. Here we discuss disc brake which is used in many vehicles. The stresses and variations developed in vented and non vented disc brakes are discussed using ANSYS software. Disc gets stressed when used in slowing down or stopping the vehicle. So that by using Ansys we can observe variations between stresses of vented and non vented disc brake. Disc brakes are mostly used on front wheels in two wheelers, hatchback cars and also widely used on both front and rear wheels of high end cars. The main aim of this paper is to minimize the Total deformation, Directional deformation, Equivalent stress and strain with best suited Material Analysis is done on both Vented and non vented disc brake. The Geometry of the models is carried out in the CATIA V5 R20 Software and is designed in Mechanical Design. The analysis part is done by using ANSYS R14.5 Software.

Differential Protection of Power Transformer in Substation

Protection scheme required for the protection of power system components against abnormal conditions such as faults etc., and that essentially consists of protective relaying and circuit breaker. Protective relay senses the fault and determines the location of fault. Then, protective relay sends the tripping command to the circuit breaker. Therefore, proper care should be taken in designing and selecting an appropriate relay which is reliable, efficient and fast in operation. The voltage transformer and current transformer continuously measure the voltage and current of an electrical system and are responsible to give feedback signals to the relays to enable then to detect abnormal conditions. This paper describes differential protection for power transformer, especially the rating of purposed system is 100 MVA, 230 kV 33 kV at substation.

Feasibility Study on Battery Energy Storage System for Mini grid

Mini grids defined as a set of electricity generators and battery energy storage system is connected between the load side and the source side. A key feature of mini grids is that they can operate autonomously with no connection to a centralized grid. Gaw Cho village, Sagaing Division, Myanmar is selected because of the higher potential of solar energy. This paper presents the unbalance condition between the load side and the source side because the solar energy is changing under weather condition. Diesel generator is used as a backup system for this proposed area but the operation of the fuel cost increased for long term period. Here, battery energy storage system is used as a secondary supplier to balance between them. This paper focus on to used HOMER software for pointing out the result outcome not be oversizing the system requirement. Using real time data, storage characteristics and HOMER simulations, optimal sizing for both approaches were established. A well design min grid offered available tool for the rural electrification system.

Analysis of Induction Generator for Geothermal Power Generation System

Nowadays, renewable energy sources contribute approximately twenty five percent of the world electricity supply. The challenge is the inevitable increase in energy consumption in the world with the risk of a major environmental impact and climate change as a results of the combustion of fossil fuels. Therefore, renewable energy has a very important role to play in the near future. Geothermal Power is one of the renewable energy sources, but it is largely ignored in favor of wind and solar energy. However, geothermal power is reliably predictable years in advance for power generation unlike wind and solar energy. Besides, it is convenient to supply the electricity sufficiently for rural and coastal areas which are far from national grid. The appropriate steam turbine to use in geothermal power plant is carefully selected. More importantly, the design calculation of a 0.5 MW, 6 poles induction generator is calculated in detail in order to generate electrical power concerned with the geothermal ranges of coastal areas in Myanmar. Geothermal power plant operations tend to be of three general kinds dry stream plants and flash plants, applied to high energy resources, and binary plants.

Expelling Information of Events from Critical Public Space using Social Sensor Big Data

Open foundation frameworks give a significant number of the administrations that are basic to the well being, working, and security of society. A considerable lot of these frameworks, in any case, need persistent physical sensor checking to have the option to recognize disappointment occasions or harm that has struck these frameworks. We propose the utilization of social sensor enormous information to recognize these occasions. We center around two primary framework frameworks, transportation and vitality, and use information from Twitter streams to identify harm to spans, expressways, gas lines, and power foundation. Through a three step filtering approach and assignment to geographical cells, we are able to filter out noise in this data to produce relevant geo located tweets identifying failure events. Applying the strategy to real world data, we demonstrate the ability of our approach to utilize social sensor big data to detect damage and failure events in these critical public infrastructures.
