Introduction To Wind Turbine on Car
A vehicle driving in the air experiences two forms of wind resistance:
- Frictional drag
- Form drag
The differences in the air pressure on the front and back sides of the vehicle drive both frictional drag and form drag. Air’s viscosity causes frictional drag, while these pressure differences cause form drag.
As the car continues to drive ahead, it will eventually be out of the air stream. When a vehicle drives through the wind, it creates turbulence or a disruption in the flow of the wind. If stationary wind turbines are positioned along the road, it will be possible to harvest energy from the wind stream that is created as a result of the movement of the vehicle. When a vehicle forms drag, it decreased, wasting energy. If the wind energy is harnessed in such a manner that it doesn’t cause any push or force in the opposite direction of the vehicle’s propulsion. The resulting power can power the vehicle’s batteries.
At the same time, minimize the vehicle’s drag to route the air to the low-pressure side. Vortex shedding prevents the air stream from entering the vehicle’s back because of this. If there are anyway for air currents to go through this area, then there will be a certain degree of reduction in the form of drag. At the same time, it can create power through the kinetic energy that the wind provides. In this area, scientists conducted several studies. However, none of them shown to have a scientific basis.
During World War II, mounted aboard submarines had wind turbines to charge their batteries while floating in the water. It’s now common to put turbines on ships, trailers, and automobiles to produce power while parked. However, since the turbine would operate as a burden for the driving vehicle. It is challenging to harvest electricity from the moving vehicle itself. A large portion of the design demonstrated that engineers put the turbine on the car top without considering the extra weight they would contribute. In addition, no efforts were made to minimize this weight. Maxx and Rory Handel developed the design with four air intakes strategically positioned. These air intakes will route the airflow over the car’s body and into the turbine. There was no accurate design available.
If the vehicle is traveling at a steady speed of 15 meters per second. Then we can assume that there is a wind stream going around the car at a speed of 15 meters per second.
In a typical scenario, the wind would provide a drag force that would push the vehicle in the opposite direction of the propulsion. To maintain a steady speed, the vehicle must resist friction and wind resistance. It is feasible to create electricity from the air streams running around the vehicle if the air flowing around the car can be brought inside the vehicle and allowed to flow down the backside.
Front stasis deflects the wind on both sides of the vehicle, which has previously interacted with this wind. Vehicles overcome aerodynamic resistance, resulting in a loss of energy. This means using traditional energy conversion techniques to recover some of the energy if the streams are collected without generating additional drag in the direction of the vehicle’s motion.
Installing a wind turbine on car is one option for accomplishing the goal. It will also assist raise the pressure at the backside, reducing the drag force. As a result, there will be a decrease in the rearward shedding of vortices.
In order to do this, it is important to make adjustments to the architecture of a vehicle so that there is enough provision for air movement through the vehicle. It’s also vital to consider the placement of the turbines since this will ensure that they don’t contribute any more drag to the vehicle. The thrust operating on the turbines may be canceled out if the turbines are positioned symmetrically.
A battery is a kind of energy storage comprised of several individual cells. Its major purpose is to create electricity through a chemical reaction that yields chemical energy which converts into electric energy and is then utilized in automobiles. In automobiles with traditional engines, the batteries have no other use except to provide electricity to various components. As a result, the pace of the battery discharge itself quite sluggishly. Batteries are the major source of power in electric vehicles (EVs). Becoming more common as the globe moves toward the manufacturing and usage of electric vehicles. Because of this, electric vehicles need batteries with a greater capacity.
High-power capacity batteries need daily recharging. Despite the fact that they’re capable of storing far more energy. These batteries need a very high-power input to charge, and the charging process takes much longer as a result. People do not favor electric vehicles as a result of this drawback. Thus, the idea is to provide a system that can charge the battery while the vehicle is in motion, i.e., charging the battery without stopping the vehicle. With wind power, the most environmentally benign and sustainable source of electricity is possible. The Vertical Axis Wind Turbine (VAWT) captures all of this available wind power. As long as the vehicle has an air intake grille, the VAWT creates power through the front grille and propels airflow. This method can cut down on both the amount of time and money needed to charge the batteries in electric vehicles.
