Influence of urban morphological characteristics on thermal environment
TL;DR: In this article, the influence of urban spatial forms on land surface temperature (LST), the spatial distribution of LST and five urban morphology indicators were analyzed, namely floor area ratio (FAR), plot ratio (PR), absolute rugosity (Ra), mean aspect ratio (λc), and sky view factor (SVF).

The numerical computation of turbulent flows
Brian Launder,D. B. Spalding +1 more
TL;DR: In this paper, the authors present a review of the applicability and applicability of numerical predictions of turbulent flow, and advocate that computational economy, range of applicability, and physical realism are best served by turbulence models in which the magnitudes of two turbulence quantities, the turbulence kinetic energy k and its dissipation rate ϵ, are calculated from transport equations solved simultaneously with those governing the mean flow behaviour.
Thermal radiation heat transfer

Local Climate Zones for Urban Temperature Studies
Iain D. Stewart,Timothy R. Oke +1 more
TL;DR: The Local Climate Zone (LCZ) classification system as discussed by the authors was developed to address the inadequacies of urban-rural description, and consists of 17 zone types at the local scale (102 to 104 m).
