The paper experimentally quantified the effect of lubricant on horizontal flow boiling of R410A. This was accomplished by first establishing a baseline by measuring the convective boiling heat transfer performance of pure R410A. The heat transfer
This paper quantifies the influence of CuO nanoparticle concentration on the boiling performance of R134a/polyolester mixtures on a roughened, horizontal flat surface. Nanofluids are liquids that contain dispersed nano-size particles. Two lubricant based
In 2006, the ASTM E57 committee was established to develop standards for 3D imaging systems. A 3D imaging system is a non-contact instrument that is used to measure the range and bearing to and/or the 3D coordinates of points on an object or within a
The application of Stereoscopic Particle Image Velocimetry (SPIV) is a new approach to quantifying the ventilation in enclosure fires. SPIV is a non-intrusive optical measurement technique which measures the displacement of tracer particles in a flow. The

A new particle-based approach is applied to the modeling of experiments on the effects of the melt flow behavior of thermoplastics. The Particle Finite Element Method (PFEM) combines convection of particles by the flow field with a finite element solution
The National Institute of Standards and Technology (NIST) has investigated the fire conditions of two very different fire training incidents that resulted in the loss of life. One incident occurred in an acquired structure and the other occurred in a
The application of Stereoscopic Particle Image Velocimetry (SPIV) is a new approach to quantifying the ventilation in enclosure fires. Stereoscopic PIV is a non-intrusive optical measurement technique which measures the displacement of tracer particles in

The National Institute of Standards and Technology (NIST) recently conducted a series of reduced-scale compartment fire experiments with the purpose of generating a database of comprehensive and accurate measurements that can be utilized both for a better
This report documents a benefit-cost analysis performed to measure the expected present value of net benefits resulting from the installation of a multipurpose network fire sprinkler system in a newly-constructed, single-family house. The benefits and
