Impact of the V CAP on induced turbulent air flow in a solar chimney a computational study
Journal of Thermal Engineering, 2023 In this paper, a 2D numerical simulation of a solar chimney with a top V cap was performed to evaluate the induced air flow degradation. Dimensions including the width of the cap and the cap offset from the top of chimney are specified as key parameters.

Aerodynamic effects on a high slenderness concrete chimney [PDF]
Revista IBRACON de Estruturas e Materiais, 2019 Abstract This paper presents the results of a theoretical-experimental study on the aerodynamic behavior of a 150m high, slenderness 30, concrete chimney. For the wind tunnel tests two scaled models were built: one rigid for the measurement of the external pressures, and other aeroelastic, in which the main dynamic characteristics of the real structure
