This applet transforms Trane's popular manual duct sizing and layout calculator into Combined 1D & 3D CFD Approach for GT Ventilation System analysis http://.enginsoft/assets/img/tecnology/cfd/newsletter11-1-Fm.pdf ASHRAE duct-fitting database provides the corresponding pressure loss coefficients. ...
The results showed that if the break is located in the hot duct halfway between the reactor vessel and the main heat exchanger, the pressure loss coefficient value falls in the range of 1.05-1.15 for break sizes up to 100%. Considering the primary importance of the hot duct break pressure...
The overall heat loss coefficient is calculated as the sum of back, side and top heat losses coefficients: 𝑈o=𝑈t+𝑈b+𝑈eUo=Ut+Ub+Ue (28) The following equations are used to determine the useful heat gain to the airflow, as well as the air mass flow rate and the Reynolds...
