This article presents experimental results of heat transfer from two different studies [1, 2] for horizontal flow boiling inside smooth copper tubes with different refrigerants. The main goal of this study was to verify the influence of the saturation temp ...
The current industrial need for compact high heat density cooling devices has conveyed an increasing interest on convective boiling in micro-channels. Although there is general agreement that these systems may be able to dissipate potentially very high hea ...
Few experimental test data are available for evaporation of ammonia inside tubes and numerous new data have been measured and presented here. An improved approach to the prediction of flow boiling heat transfer in horizontal tubes has been proposed through ...
We perform detailed finite element simulations of impact of metallic plates by spherical particles over a range of impact angles and speeds with a view to develop an insight into the fundamental mechanisms underlying solid-particle erosion. The particular ...
The substitution of CFC refrigerants in refrigeration systems, heat pumps and organic Rankine cycles, requests a good knowledge of the heat transfer and pressure drop properties of substitute fluids. A contribution to this international effort is proposed ...
A new optical void fraction measurement system has been coupled to the existing LTCM flow boiling test facility to obtain dynamic and time-averaged void fractions, simultaneously with measurements of the local heat transfer coefficients. A series of evapor ...
In this paper we consider (hierarchical, Lagrange) reduced basis approximation and a posteriori error estimation for linear functional outputs of affinely parametrized elliptic coercive partial differential equations. The essential ingredients are (primal- ...
This paper analyzes by numerical simulation the formation, the fragmentation, and the penetration in a plate of a copper jet that develops in a shaped charge. A finite element Lagrangian code has been used to gain insight into this problem. The study is co ...
A novel bench-scale calorimeter, which is based on a heat-flux principle and modified to accommodate biol. reactions, was evaluated for detg. the heat evolution rate of an aerobic culture of the yeast Kluyveromyces fragilis grown on lactose. The instantane ...
A truly meshless method based on the weighted least-squares (WLS) approximation and the method of point collocation is proposed to solve heat conduction problems in heterogeneous media. It is shown that, in the case of strong heterogeneity, accurate and sm ...
