TL;DR: In this paper, a new method of momentum theory was proposed to investigate human motion induced effects on indoor environments (i.e., momentum source implemented into Navier-Stokes equations to simulate human/objects moving).

TL;DR: In this paper, the influence of air change rates on indoor CO2 stratification and removal with dimensionless time scale ratio (proportional to Ri/α, Richardson number Ri, mass flux ratio α) and vorticity by applying experiment and simulation methods.

TL;DR: In this article, the authors presented a systematic study focusing on the ventilation rate of the ground source heat pump (GSHP) system from the perspective of energy saving and indoor thermal comfort combined, and constructed the mathematical model of PMV and power connected by ventilation rate through a full-scale GSHP system.

TL;DR: In this article, the authors evaluated the performance of several turbulence models, including the standard k − ǫ model, low Reynolds number k-ǫ models, the v2f model, large eddy simulation (LES) models, and Detached Eddy Simulation (DES) models for simulating the pressure drop and transitional flows through pleated filters both with and without an electrostatic precipitator.

TL;DR: In this article, a hybrid electrostatic filtration system (HEFS), which combines an electrostatic precipitator (ESP) and a fibrous filter installed downstream of the ESP, was investigated experimentally.
