Wang, Z., Alajbegovic, A., Han, J., Donley, T. et al., "Long Term Transient Cooling of Heavy Vehicle Cabin Compartments," SAE Technical Paper 2010-01-2018, 2010, doi:10.4271/2010-01-2018.
A newly developed simulation methodology for a long term, transient tractor cabin cool-down is presented in this paper. The air flow was simulated using a Lattice-Boltzmann Equation (LBE) based 3-dimensional flow solver. The conduction and radiation effects on the solid parts as well as the average cabin air temperature evolution were solved by the thermal solver, which also includes a human comfort model. The simulation results were compared with the measured experimental test data and good agreement was observed validating the developed simulation approach. The developed methodology can be applied to all other ground vehicles cabin comfort applications.
