“…Some hyperthermia deaths due to solar heating have occurred at relatively low ambient temperatures (eg, 57°F/14°C, 60°F/16°C, 66°F/19°C, 67°F/19°C), however, the vehicular temperatures associated with those deaths is unknown 1. Climate researchers have created models to project maximum vehicle temperatures and human heat balance of a small child inside an enclosed vehicle 8 21 22. These models may be useful to medical examiners in estimating time of death and to child safety advocates in educating about the risks of leaving children unattended in vehicles.…”

“…Therefore, trunk temperatures could only be surmised based on internal car temperatures recorded in the passenger area of the car. Experiments inside vehicles in Western Australia showed that trunk temperatures were usually 10˚C higher than ambient temperatures whereas passenger area temperatures could be as much as 20-30˚C higher than ambient, reaching almost 70˚C, on days with ambient temperatures near 40˚C [32]. It was also noted that the internal temperatures within a dark car were almost 5˚C higher than a white car under identical hot summer daytime conditions [32].…”

The present experiments were conducted under the much cooler summertime temperatures of southwestern British Columbia, with ambient temperatures very rarely above 25˚C, dropping to as low as almost 10˚C on some nights (Fig 1).…”

In order to investigate the impact of confinement in a car trunk on decomposition and insect colonization of carcasses, three freshly killed pig (Sus scrofa domesticus Erxleben) carcasses were placed individually in the trunks of older model cars and deployed in a forested area in the southwestern region of British Columbia, Canada, together with three freshly killed carcasses which were exposed in insect-accessible protective cages in the same forest. Decomposition rate and insect colonization of all carcasses were examined twice a week for four weeks. The exposed carcasses were colonized immediately by Calliphora latifrons Hough and Calliphora vomitoria (L.) followed by Lucilia illustris (Meigen), Phormia regina (Meigen) and Protophormia terraenovae (R.-D.) (Diptera: Calliphoridae). There was a delay of three to six days before the confined carcasses were colonized, first by P. regina, followed by Pr. terraenovae. These species represented the vast majority of blow fly species on the confined carcasses. Despite the delay in colonization, decomposition progressed much more rapidly in two of the confined carcasses in comparison with the exposed carcasses due to the greatly increased temperatures inside the vehicles, with the complete skeletonization of two of the confined carcasses ocurring between nine and 13 days after death. One confined carcass was an anomaly, attracting much fewer insects, supporting fewer larval calliphorids and decomposing much more slowly than other carcasses, despite similarly increased temperatures. It was later discovered that the vehicle in which this carcass was confined had a solid metal fire wall between the passenger area and the trunk, which served to reduce insect access and release of odors. These data may be extremely valuable when analyzing cadavers found inside vehicle trunks. Highlights • Confinement of pig carcasses inside car trunks in southwestern British Columbia, Canada delayed blow fly colonization by three to six days • Temperatures inside cars were much higher than ambient temperatures and speeded up decomposition of the confined carcasses

“…Simion et al [2] examined the factors which influence thermal discomfort inside the vehicle and found out that the temperature and relative humidity are the two most important factors influencing human comfort. Another problem associated with excessive heat is heat stokes which mainly affects children and pets [3,4]. Grundstein et al [5] examined the cabin temperature under different meteorological conditions and found out that even in cloudy days with lower ambient temperature, the vehicle cabin temperature can reach deadly level.…”

A B S T R A C TIn this work both experimental and numerical analysis are carried out to investigate the effect of solar radiation on the cabin air temperature of Maruti Suzuki Celerio car parked for 90 min under solar load condition. The experimental and numerical analysis encompasses on temperature increment of air at various locations inside the vehicle cabin. The effect of 90 min exposure to the environment is simulated with the help of Discrete Ordinance (DO) and Surface to Surface (S2S) radiation models using ANSYS FLUENT 18.2. Moreover, the impacts of using different turbulence model on the accuracy of the simulation results and the comparison between steady state and transient state simulation results have also been studied. The results of the simulation are compared with the experimental data to contrast the model. The absolute average deviation in temperature predicted by DO and S2S model from the experimental data are 10.08 and 10.01%, respectively.
