Heat exchangers are used in a variety of industrial and technical settings. The design of heat exchangers is fairly sophisticated, since it necessitates an accurate study of heat transfer rate and pressure drop estimates, as well as considerations like as long-term performance and cost. Whenever heat transfer inserts are employyed, Along with the rise in heat transfer rate, the pressure drop increases as well. The pressure has risen.Energy conservation is critical for both industrial development and environmental impact reduction. Because of current energy prices, the need for energy conservation is rising. More resourceful gadgets can help reduce energy costs. In the refrigeration, automotive, chemical, and process sectors, heat exchangers are the most significant device. As a result, there is a demand in the industrial sector for heat exchangers that are less expensive, more efficient, and smaller. Inserts in channels are widely employed as part of a passive heat transfer augmentation technique.

India is a second most populous country in the world. So, in day to day use people uses vehicles for their daily purpose and it causes heavy traffic on the roads. Hence it is very time consuming and difficult for the ambulances to avoid the traffic and reach to the hospital as early as possible. We developed a Smart Ambulance Service that alerts to traffic police who is present on the same route from where the Ambulance is passing. It notifies the traffic police when Ambulance is 1 km away from him.
