Development and Performance Evaluation of Vehicle-Mounted Wind Turbine for Electrical Power Generation | Chapter 2 | Current Concepts in Engineering Research and Technology Vol. 1

Environmental degradation from continuous use of fossil fuels and the attendant effects on human and animal environments demand sustainable, renewable energy alternatives to protect the environment from further deterioration. Wind energy offers a promising solution as it is available everywhere, inexhaustible, and can be accessed anytime for the continuous powering of electric vehicles while in motion. The present study aims to investigate the effects of wind speed, car speed, and altitude on power generation using a vehicle-mounted wind turbine (VMWT) on a moving vehicle. A VMWT was developed and tested at varying altitudes, wind and vehicle speeds across the northern and southern zones of Nigeria to assess its energy generation potential for use in powering electric vehicles. The Horizontal axis wind turbine (HAWT) utilised a dynamo rated at 12V 10 W at 325 rpm, a swept area of 0.159 m2 operating directly without a mechanical multiplier system, a cup anemometer and a data logger to capture real-time data. The data obtained was analysed using analysis of variance (ANOVA) SPSS16 and Minitab software and Design Expert.v.18. The data obtained was grouped using six driving speed ranges (0-20km/hr,20- 40km/hr,40-60km/hr,60-80km/hr,80-100km/hr and 100-120km/hr), four altitude ranges (0- 100m,100-200m,200-300m, and 300-400m) and four wind speed ranges (0-50m/s,50-100m/s,200- 250m/s and above 250m/s). The lowest mean wind speed of 8.68m/s was recorded at a car driving speed range of 0-20km/hr and at an altitude range of 0-100m and the mean power generated was 266.476mW, while the highest mean wind speed of 108.47m/s occurred at a driving speed range of 100-120km/hr at altitude range of 100-200m with a peak electrical power of 6479.242mW. The peak power output of 6662.131mW for this research was recorded at the altitude range of 300-400m, driving speed range of 100-120km/hr and wind speed 570m/s. This output can be further enhanced by utilising both a mechanical multiplier and a buck-boost converter to efficiently charge the car battery, thereby extending the vehicle's driving range. The result of this Study shows that electrical power generation increased with higher vehicle speeds and wind speeds across all altitude ranges. Further studies are required to be carried out on the turbine blades for increased power generation.

Fuzzy Rule Suram for Controlling Drying Process System | Chapter 1 | Techniques and Innovation in Engineering Research Vol. 5

 The invention of Fuzzy Rule Suram to control the drying process system is completed activity in order to get optimal strength use. In its exercise, Fuzzy Rule Suram uses The look-up tables. The look-up table is the actuator plant to do the advantage of fuzzification. Rule Suram is based on fluffy philosophy and has two weather variables: ambient hotness and humidity. It is secondhand in the wood drying process. The mistake value and change mistake of the membership function of united states of america variable are presented by the usual triangle and trapezium maps. The study resulted in four fluffy rules in 81 conditions to control the production system, that can be innate a difference of weather and air conditions. It is used to lower the heater's energetic energy use. One cycle of due drying is a serial of the condition of the room to process as use as a wood variety. In its incident, the Suram Fuzzy Rule Algorithm to control the drying process system allows for possibility the addition of additional influencing variables. Extended fluffy rule Suram is an algorithm grown to control a drying structure using engine as an energy beginning by modifying the profit of the fuzzy enrollment function {0.5,1]; and has been grown taking into account the wind speed in the exercise of the fuzzy rule for drying espresso, dan The results of the analysis show that maximizing the use of solar radiation reaches 40.86%.

Study on the Influence of Longitudinal Diffusion on the Transport of Dust Particles Emitted from a Fixed Source | Chapter 1 | Current Topics on Mathematics and Computer Science Vol. 6

 The diffusion of dust particles released from a fixed source in the presence of longitudinal diffusion and the lack of latitudinal and vertical diffusions is explored using a mathematical model. The atmospheric diffusion equation governs the dispersal of dust particles in the atmosphere. The general situation of the time-dependent diffusion equation in the presence of a point source whose strength is dependent on time was solved in the earlier study [1]. Diffusion factors play a crucial influence in the distribution of dust particles in the atmosphere, according to the estimates. We looked at the model in the previous paper in the presence of Vertical diffusion and the absence of other diffusions show that the dust spreads with a front that moves at the speed of the wind for short periods of time. We will assume that the flow is a non-zero constant in this investigation. The vertical and latitudinal diffusions are absent in this study, but the longitudinal diffusion is present. The solution is discovered to be dependent on the cause of temporal dependence. Two particular situations of the source are provided to explore the nature of the solution. There is no discontinuity front in either instance, and the dust particles move slowly in the direction of the wind.
