CloudFlame is a cloud-based cyberinfrastructure for managing combustion research and enabling collaboration. It consists of a joint cloud venture with PrIMe and an independently hosted cloud to provide access to open-source simulations, a digitized data
warehouse, and various fuel design tools [1-3].
When employed by researchers at the Clean Combustion Research Center at King Abdullah University of Science & Technology and its collaborating partners, the system resulted in significantly improved flexibility and portability of kinetics data and increased efficiency, scalability, and accessibility to computational resources.
CloudFlame presents a new and exciting paradigm for collaboration in combustion and kinetics research that will enable future advances in computational chemistry, kinetic model development, experimental data management, uncertainty quantification, and reactive flow simulation.
CloudFlame equips the user with an array of tools, which perform diverse and intricate computations. These include flame speed calculations, ignition delay calculations, and simulations of plug flow reactors, counterflow diffusion flames, and perfectly
stirred reactors. These computations provide valuable data to engine designers for analyzing the combustion kinetics of various fuels.
These tools are developed using open source frameworks, which make them freely available and may be redistributed and modified. As a result, there are no licensing costs for the simulation features that CloudFlame provides. These frameworks include Cantera and OpenSMOKE++ for performing different simulations.
Cantera is a suite of object-oriented software tools for problems involving chemical kinetics, thermodynamics, and/or transport processes. OpenSMOKE ++ is a general framework for numerical simulations of reacting systems with detailed kinetic mechanisms, including thousands of chemical species and reactions.
CloudFlame’s remote solution extends the well-established PriMe architecture to enhance the experience of current PriMe users with access to various well-developed simulation apps. User can choose CloudFlame modules in PrIME to perform ignition delay and flame speed calculations.
Currently, the team is developing kinetic mechanism reduction tools and HCCI engine simulations to be included in CloudFlame.
When it comes to analyzing and understanding data sets, it may be very cumbersome to look at spreadsheets and try to interpret the data. As a result, visualization is an incredibly versatile way to give depth and meaning to data sets.
In CloudFlame, we are currently in the process of developing a cloud based visualization application that will allow a user to input data parameters, request a simulation to run, and then have access to a loadable web visualization.
When the user inputs their parameters, a simulation will be run based on the input values, and when the simulation finishes, the user profile will be updated with the simulation results.
Afterwards, the user can go onto the visualization page and load their visualization. The visualization tool allows manipulation of what dimension is being rendered (i.e, temperature, velocity, pressure, etc.), as well as the speed of the visualization and the ability to look at individual frames of the simulation.
As a result, this visualization software gives access to many different combustion related simulations to allow scientists, teachers and the entire research community to better understand the data they receive from tests and experiments.
The module introduces a set of web based tools to calculate thermodynamics data using Benson’s group additivity method. . Calculations mainly include entropy, enthalpy and heat capacity at different temperatures. The system gives a flexibility
to add as many radicals as the user needs; these radicals are calculated based on the parent molecule, as well as the selected Bond Dissociation group (BDE group). It also allows the user to generate new species, save the results under his account,
and generate a NASA polynomial fit. User can also add the generated NASA polynomial fit to a mechanism file under the user’s account, so that they can download the data as CHEMKIN thermodynamic input file (*.dat).
An important feature is that the researchers can upload their own group databases and can select which database to use in calculations.
