碩士 / 國立高雄應用科技大學 / 應用工程科學研究所 / 99 / In view of limited oil and the rise of environmental protection, the development and use of clean recyclable energy has become global consensus, among which the development of solar vehicle has become the focus of the world.“Apollo Solar car”developed by K.U.A.S.is the classic works.“Apollo Solar car” is a racing car, which stresses design of low wind resistance for reducing wind resistance. However, the cockpit space is small and hot, so it is necessary to pay high attention to the comfort and cooling system, to prevent driver can’t concentrate on driving which is dangerous. Therefore, the comfort design of cockpit is a very important subject.
The study uses the measured data as boundary condition and calculated velocity and temperature field inside the cockpit of Apollo solar car no. 6, which provides the reference of solar car design in the future by changing the speed, size and location of air inlet. In terms of experiment, I measured the speed and temperature of air inlet, the temperature and relative humidity around the cockpit is measured when the solar car is static and on the move. In terms of numerical simulation, I used STAR CCM+ is used to measure formula for Navier-Stokes and k-ε in finite-volume method regardless chemical reaction, gravity and radiative heat transfer. First, I analyzed velocity and temperature field inside the cockpit of origin program. Second, I investigated the index of predicated mean vote (PMV) and predicated percent of dissatisfied (PPD) is investigated and the improvements based on the results is proposed. The first program was increasing the air inlet and changing the location of air outlet to the lower rear corner, which improves the low-speed problem of the driver’s chest and leg. The second program was changing the location of air inlet to the front of leg and air outlet to the lower rear corner, which improving air circulation inside the cockpit in order to achieve whole improved comfort quality of driver.
The results show that the chest and leg of human body on original program whose cockpit with a human body model is in the range of discomfort. The first program shows that the PMV of human body was more closer to the comfort range when sectional area of air inlet increased twice and speed of wind improved to 10m/s , 20m/s and 30m/s, but the PMV of leg still was discomfort. The second program changed the location of original air inlet to the front of feet and shows PMV of both the chest and leg within the comfort range. Therefore, the second program improved the whole discomfort of driver inside the cockpit significantly.
