Study of the evaporation and combustion regimes of renewable liquid fuels. Single droplet imaging is used to perform the study. The experiments are carried out on two selected fuels by varying the pressure (0.1 MPa, 0.3 MPa, 0.6 MPa) and the oxygen content (21%, 10%, 0 -pure pyrolysis). The fuels are second/third generation biofuels or fundamental biofuel surrogates.Principal Investigator(s)

The ICE-GA uses the Combustion Integrated Rack (CIR) and the associated Multi-user Droplet Combustion Apparatus (MDCA) that is currently in-orbit aboard the ISS. Fuels provided by ASI to NASA will be flown to ISS in MDCA fuel reservoirs. Two reservoirs are anticipated to be required to fulfill the ASI ICE-GA science matrix. An additional diluent gas bottle will be flown to supply sufficient gas pressure and volume within the MDCA chamber. A fiber arm assembly will be flown that can hold a fuel droplet in place such that it does not float out of the field of view. A matched pair of fuel deployment needles may also be required to ensure that the current needles do not contaminate the ASI bio-fuels with previously run fuels.
Information PendingEarth Applications
After initial experiment set-up by the crew, operations are conducted from the ground. Two powered operational configurations are planned, test point acquisitions and data downlink operation. These are expected to occur on separate powered operational days. Typical test point operation will require 1000 watts of power and a video downlink channel for observation of test phenomenon. Digital video data is captured and stored on CIR provided equipment for downlink on separate days. Data downlink days require the ISS HRDL interface with desired allocation of 20 Mbps.Operational Protocols
