RISLinking BIM Definition, BIM Capability Maturity, and Integrated Project Delivery in the AECO Industry: The Influences of BIM Diffusion and Moral Hazard
Publisher: ASCE
Abstract: Based on an increasing amount of attention paid to explore why building information modeling (BIM) application levels are so low and what are the obstacles that hinder the further application of BIM, a range of existing ...
An Investigation of Treating Adiabatic Wall Temperature as the Driving Temperature in Film Cooling Studies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In film cooling heat transfer analysis, one of the core concepts is to deem film cooled adiabatic wall temperature (Taw ) as the driving potential for the actual heat flux over the film-cooled ...
Investigation of Potential Benefits of Using Bricks of High Thermal Capacity and Conductivity in a Rotating Calcining Kiln
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Petroleum coke is processed into calcined coke in a rotary kiln, where the temperature profiles of flue gas and coke bed are highly nonuniform due to different flow and combustion mechanisms. ...
Simulation of Combustion and Thermal-Flow Inside a Petroleum Coke Rotary Calcining Kiln—Part I: Process Review and Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Calcined coke is an important material for making carbon anodes for smelting alumina to aluminum. Calcining is an energy intensive industry and a significant amount of heat is wasted in the ...
Simulation of Combustion and Thermal-Flow Inside a Petroleum Coke Rotary Calcining Kiln—Part II: Analysis of Effects of Tertiary Airflow and Rotation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A computational model is established to simulate the combustion and thermal-flow behavior inside a petcoke rotary calcining kiln. The results show that peak temperature is located at the tertiary ...
Investigation of the Coal Gasification Process Under Various Operating Conditions Inside a Two-Stage Entrained Flow Gasifier
