Assessment of high-heat-flux thermal management schemes
TL;DR: This paper explores the recent research developments in high-heat-flux thermal management and demonstrates that, while different cooling options can be tailored to the specific needs of individual applications, system considerations always play a paramount role in determining the most suitable cooling scheme.

Review of spray cooling – Part 1: Single-phase and nucleate boiling regimes, and critical heat flux
TL;DR: In this article, a review of spray cooling is presented, focusing on the relatively high-flux, low-temperature mechanisms and predictive tools associated with the single-phase liquid cooling and nucleate boiling regimes, as well as critical heat flux (CHF).
Journal ArticleDOI

Optimizing and Predicting CHF in Spray Cooling of a Square Surface
Issam Mudawar,Kurt A. Estes +1 more
TL;DR: In this paper, the effect of volumetric flux distribution on critical heat flux (CHF) on spray cooling of a hot surface was investigated, and it was determined that CHF can be maximized when the spray is configured such that the spray impact area just inscribes the square surface of the heater.

Phase/Doppler Spray Analyzer For Simultaneous Measurements Of Drop Size And Velocity Distributions
W. D. Bachalo,M. J. Houser +1 more
TL;DR: In this paper, the interference fringe pattern produced by spheres passing through the intersection of two laser beams was used for measuring the size and velocity of spherical particles. But the results of the experiments were limited to the case of monodisperse droplet streams.
Journal ArticleDOI
Nonlinear estimation applied to the nonlinear inverse heat conduction problem
TL;DR: In this article, a finite-difference method based on the concepts of a general technique for solving inverse problems called nonlinear estimation is proposed. But the method requires future temperatures when small time steps are to be used.

Determination of the Local Quench Curve for Spray-Cooled Metallic Surfaces
Issam Mudawar,W. S. Valentine +1 more
TL;DR: In this paper, an experimental study of heat transfer from hot metallic surfaces to water sprays was conducted in the single-phase, nucleate boiling, and transition boiling regimes of the quench curve for surface temperatures below 400° C.

Mechanisms of film boiling heat transfer of normally impacting spray
K.J. Choi,Shi-Chune Yao +1 more
TL;DR: In this paper, the heat transfer mechanisms of horizontally impacting sprays were studied experimentally and an impulse-jet liquid spray system and a solid particle spray system were used to produce uniform droplets with independent variables of droplet size, velocity, liquid flow rate, and air velocity.

Film and Transition Boiling Correlations for Quenching of Hot Surfaces with Water Sprays
TL;DR: In this paper, spray quenching experiments were performed with water sprays to correlate heat fluxq′' to surface-to-fluid temperature difference AT, and the local values for the spray hydrodynamic parameters of volumetric fluxQ′', mean drop velocityUm and Sauter mean drop diameterd32 over a wide range of operating conditions (Q′’ = 0.137-1.350 mm), and surface temperatures up to 520° C.
