Description
In this work the results of numerical computation applied to X-ray absorption by fuel sprays are reported. A radiation source of Cu K X-ray tube in combination with a polycapillary halflens has been simulated with the emerging radiation impacted on a CCD detector. A 3D software reproduces both parallel and low divergent X-ray beams irradiating the samples of various shapes and different transmitting media. To evaluate X-ray propagation in fuel sprays, which are practically transparent at X-ray frequencies, we have simulated the fuel sprays with the additive of Cerium at different concentrations that allows the X-ray absorption to be enhanced. The density of a spray has been simulated by having varied both number and shape of the droplets over the X-ray optical path.
Rotating irradiated sample around the radiation propagation axis has been simulated for a tomography reconstruction with successful resulting images.
