AFT - Version Arrow 9 -Calculate Compressible Flow Software
AFT Arrow is a fluid dynamic simulation tool used to calculate pressure drop and flow distribution in gas piping and ducting systems. Accurately simulate individual components and their interaction including effects of heat transfer, real gases and choked flow. Tightly integrate equipment characteristics, analysis and output with your system’s schematic representation. Utilize a wide array of features without sacrificing your need for a short learning curve. Compare the performance of new designs and assure all design requirements are met. Identify and correct operational problems in installed systems. Significantly improve the quality of systems engineering and produces less costly, more efficient and more reliable piping systems.
