Photograph of the Conical-Shaped Fire Pattern along a concrete block wall (fire origin was located underneath the stack of wooden pallets-fire test executed at EKU by author)
From this perform, Ngu developed a Software based upon a relentless spring power along with a pressure probe. Ngu executed easy bench top tests to evaluate this Software’s capability to reliably get hold of depth measurements. Ngu didn't examination this methodology for software towards comprehensive-scale fires for investigation uses.
