An on-off regulation method by predicting the valve on-time ratio in district heating system
Building Simulation, 2015Good room temperature control is beneficial for users’ thermal comfort and health. It also helps reduce energy consumption and carbon dioxide emissions inside the buildings. However, there are certain limitations with the current thermostatic valves commonly used in central heating systems, especially the ones used in China, since they cannot ...

Abstract The current finite difference lattice Boltzmann method (FDLBM) gives a fixed specific heat ratio because internal energy is limited to the translational freedom of the space. Yan et al. and Kataoka et al. clarified the conditions for deriving models with arbitrary specific heat ratio and proposed Euler models.

Abstract An analysis technique is outlined that calculates the sensible and latent heat fluxes by the Bowen ratio and aerodynamic methods, using profile measurements at any number of heights. Field measurements at two sites near Churchill, Manitoba, comprising over 4000 hours of data from June through September, are used to assess the relative accuracy

Transpiration of plantation pinus radiata estimated by the heat pulse method and the bowen ratio
Hydrological Processes, 1990AbstractThe heat pulse method was used to estimate stand transpiration from a radiata pine (Pinus radiata) plantation in southeastern Australia over a period of four days. The diurnal pattern of sapflow was related to net radiation with a time lag of about 1.5 hours.

A conservative phase-field lattice Boltzmann method for boiling heat transfer at high density ratios
Physics of FluidsThis work presents a conservative phase-field lattice Boltzmann method (LBM) for boiling heat transfer at high density ratios. This method employs the LBM for modeling unsteady flows, the finite difference method for solving the heat transfer equation, and the conservative phase-field method as the interface tracking model.
