Co-simulation of building energy simulation and computational fluid dynamics for whole-building heat, air and moisture engineering

On the thermal performance of naturally ventilated room with straw insulation retrofitted envelope for different climatic zones of India

“…Therefore, this brief review covers only recent studies that use CFD tools for analysing indoor airflow and thermal performance of ventilated or unconditioned spaces, some of which are used as references for choosing appropriate simulation parameters. Transient simulation of hygrothermal performance of buildings was carried out by Mirsadeghi [54]. The author had used experimental results available in previous literature to validate the simulations employing standard k-ω model along with low-Re correction and Boussinesq approximation.…”

“…For this purpose, two references from literature dealing with different conditions of indoor air simulation are used here. The first is the work by Mirsadeghi [54] in which the author compared the results of transient thermal analysis of an enclosed space using three different methods: material properties, mesh, and simulation parameters were the same as those used in the reference.…”

“…Figure3: The models used in the references selected for validation: (a) transient simulation of an enclosed space[54] and (b) steady-state simulation and experiment comparative study of a ventilated space[58].…”

“…Figure5: Comparison of the results between the reference and current simulation: (a) average indoor air temperature[54] (b) average inside surface temperature of the north wall[54], and (c) inside surface temperature variation near the hot wall[58].…”
