Journal Article
Ji, Y., Zhang, Y., Korolija, I., & Futcher, J. (2016). Design summer year weather - outdoor warmth ranking metrics and their numerical verification. Building Services Engineering Research and Technology, 37(6), 639-663. https://doi.org/10.1177/0143624416648179

The existing methods of selecting design summer year weather data rely on the outdoor dry bulb temperature without considering solar radiation and wind which can impact on indoor thermal conditions. This research sets out to examine the existing out... Read More about Design summer year weather - outdoor warmth ranking metrics and their numerical verification.

Assessing overheating of the UK existing dwellings – a case study of replica Victorian end terrace house (2014)
Journal Article
Ji, Y., Fitton, R., Swan, W., & Webster, P. (2014). Assessing overheating of the UK existing dwellings – a case study of replica Victorian end terrace house. Building and Environment, 77, 1-11. https://doi.org/10.1016/j.buildenv.2014.03.012

This paper aims to investigate the likely thermal performance of a unique pre-1919 Victorian case study property by using both current and future projected weather data after a deep retrofit. The property is a re-construction within an environmental... Read More about Assessing overheating of the UK existing dwellings – a case study of replica Victorian end terrace house.

CFD modelling of natural convection in air cavities (2014)
Journal Article
Ji, Y. (2014). CFD modelling of natural convection in air cavities. CFD Letters, 6(1), 15-31

This paper discusses the modelling of natural convection in air cavities using four eddy viscosity turbulence models. Two 2D closed cavities with deferentially heated walls opposite each other and one 3D open ended tall cavity with one side is heate...

The role of diffusion on the interface thickness in a ventilated filling box (2010)
Journal Article
Kaye, N., Flynn, M., Cook, M., & Ji, Y. (2010). The role of diffusion on the interface thickness in a ventilated filling box. Journal of Fluid Mechanics, 652, 195-205. https://doi.org/10.1017/S0022112010000881

We examine the role of diffusivity, whether molecular or turbulent, on the steady-state stratification in a ventilated filling box. The buoyancy-driven displacement ventilation model of Linden et al. (J. Fluid Mech., vol. 212, 1990, p. 309) predicts... Read More about The role of diffusion on the interface thickness in a ventilated filling box.

Hybrid ventilation for low energy building design in south China (2009)
Journal Article
Ji, Y., Lomas, K., & Cook, M. (2009). Hybrid ventilation for low energy building design in south China. Building and Environment, 44(11), 2245-2255. https://doi.org/10.1016/j.buildenv.2009.02.015

Buildings and their related activities are responsible for a large portion of the energy consumed in China. It is therefore worthwhile to investigate methods for improving the energy efficiency of buildings. This paper describes a low energy building...
