This study assesses global efforts to enhance existing ammonia plants and explores the feasibility of integrating heat exchangers at different stages of ammonia production. Based on this, the researchers analyzed two heat exchange systems, namely the NH3-H2 shell and tube heat exchanger and the H2O-to-H2O helical heat exchanger, in order to investi...
This research focuses on enhancing natural ventilation in multifamily residential buildings to improve air quality and minimize reliance on mechanical ventilation, thereby reducing energy consumption. The study pioneers the integration of passive pipe systems within structural floor slabs and building envelopes, aiming to overcome the inherent chal...
This research study utilizes Computational Fluid Dynamics (CFD) to investigate the impact of adjusting Free Flow Paths (FFPs) in office space with the aim of minimizing infection risks. The study examines five design scenarios; Double 2m, Triple 2m Single 4m, 4m and Triple 6m, in comparison to the base case (Single 2m). The evaluations conducted in...
