This paper reports on the development and evaluation of a novel hybrid method for obtaining heat flux measurements. By combining spatial and temporal temperature measurements, it is shown that both the time response and accuracy of a heat flux sensor can be improved. This hybrid method was shown to increase the time response of a heat flux sensor mounted on(More)
Water tunnel experiments have been performed to examine how large scale, high intensity freestream turbulence affects heat transfer through a laminar flat plate boundary layer. Time-Resolved Digital Particle Image Velocimetry (TRDPIV) was used to examine the flow field along with time-resolved heat transfer from the wall. The surface heat flux was measured(More)
OBJECTIVE In 2010, the National Children's Study launched 3 alternative recruitment methods to test possible improvements in efficiency compared with traditional household-based recruitment and participant enrollment. In 2012, a fourth method, provider-based sampling (PBS), tested a probability-based sampling of prenatal provider locations supplemented by a(More)
