Air flow through alveolaCFDAL is special software to model the air flow within the alveola, including particle tracking, and was developed in collaboration with the Harvard School of Public Health. The software also provides information about the velocity and pressure fields, particle tracking and streamlines (with detection of the stagnation point.) CFDAL represents an innovative software environment for the alveolated duct flow in rhythmically expanding pulmonary acinus. The complete object-oriented method is implemented and the program runs on the Windows platform. Computational fluid dynamics (CFD) is essential for simulating the human physiological flows. Non-engineering professionals, especially medical doctors or biomedical researchers, will find general-purpose software for CFD analysis a complicated affair. However, CFDAL provides automation, eliminates user-dependent mistakes, drastically reduces time to generate the computer model, so that there is no need for the user to know the details of pre-processing procedures for CFD computer analysis. Availability of the software for transfer data in other Windows applications is supported automatically. The OpenGL inside C++ language is used for building the graphical user interface. CFDAL is developed for the simulation of tidal breathing by an automatic generation of a realistic geometric model of an alveolated duct that expands and contracts. Acinar fluid mechanics plays an important role in explaining aerosol deposition, chaotic mixing and other phenomena in the lung periphery. CFDAL can be used as a tool to optimize the design of devices in the aerosol industry. Velocity field  | Fluid particle trajectories  |
