“…Thermal network models, also known as resistance-capacitance (RC) networks, introduced by Beuken [1] and then rapidly developed in combination with the lumped capacitance method by other researchers, are widely used in a transient heat flow analysis at relatively low computational costs [2]. They are frequently employed in the thermal modelling of different physical objects of various complexities, such as the hard disk drive [3], the two-phase closed thermosyphon [4], the high-power LED light [5], the combustion chamber of the diesel engine [6], or the passive-cooled battery pack [7]. In addition to these problems, thermal networks are commonly used in building-related simulations.…”

This paper presents an application of the Simulink stvmgain S-function for the thermal modelling of a building zone based on the resistance–capacitance scheme of EN ISO 13790. That model in the form of the state-space matrix with time-varying elements was used in simulations of a building with hourly and, suggested in that standard, daily averaged ventilation airflow in five European cities. The following two ventilation schedules were used: occupancy-based; and wind-dependent. Comparative simulations were conducted in EnergyPlus. In general, the results obtained for the annual heating and cooling demand were better for hourly than daily averaged ventilation with an error below 10%. However, in several cases of cooling, the error was above 30%. When considering hourly indoor air temperatures, the proposed method provided very good results with MAE of up to 0.52 °C and 0.46 °C, RMSE < 0.69 °C and 0.62 °C, and CV(RMSE) < 3.09% and 2.75% for the daily averaged and hourly ventilation flow, respectively. For wind-driven ventilation, the temperatures were as follows: MAE < 0.49 °C and 0.48 °C; RMSE < 0.69 °C and 0.68 °C; and CV(RMSE) < 3.01% and 2.97%.

Abstract-In order to improve the precision of quasi-dimensional model for predicting diesel engine performance, three kinds of air entrainment period in quasi-dimensional model for diesel engine working process is developed in this research. The software MATLAB/Simulink is utilized to build the quasi-dimensional model for diesel engine and different kinds of air entrainment period effect on the performance prediction of diesel engine are simulated. The simulation results show that the relative errors of diesel engine performance between three methods are obvious different at rated working condition. It can be concluded that the proper method to calculate air entrainment period must be selected to improve performance prediction precision of simulation model.
