This paper presents a numerical study of natural convection within a wavy enclosure heated via corner heating. The considered enclosure is a square enclosure with left wavy side wall. The vertical wavy wall of the enclosure and both of the corner heaters are maintained at constant temperature, T c and T h , respectively, with T h > T c while the remaining horizontal, bottom, top and side walls ...

Analytical models are presented for conduction shape factors for three-dimensional regions formed between an isothermal, arbitrarily shaped body and its concentric, arbitrarily shaped surrounding enclosure. The model is based on the exact solution for the concentric spheres, and two methods are developed to predict the effective gap spacing. The models are validated using existing numerical dat...

introduction: the purpose of this in vitro study was to compare the accuracy of working length determination using the apex locator versus conventional radiography in c-shaped canals. methods and materials: after confirming the actual c-shaped anatomy using cone-beam computed tomography (cbct), 22 extracted c-shaped mandibular second molars were selected and decoronated at the cemento-enamel ju...

Most portable diesel generators (often referred to as gensets) produce high sound power levels. The sound generated by various internal components of the genset is transmitted to the far field by two radiation mechanisms: sound transmits through the panels of the generator enclosure as well as propagates through any openings in the enclosure. In order to determine which mechanism to control, a ...

An algorithm and a robust floating point implementation is given for rotational polygon containment: given polygons P1,P2,P3, . . . ,Pk and a container polygon C, find rotations and translations for the k polygons that place them into the container without overlapping. A version of the algorithm and implementation also solves rotational minimum enclosure: given a class C of container polygons, ...

In present study, a 2D rectangular enclosure was considered as latent thermal energy storage (LTES) system. Lauric acid used PCM material. The aim of this study to use fins enhance melting process PCM. Position and shape double were investigating parameters. At first stage three different positions for shape. Results indicated that amongst aforementioned cases, best results achieved when locate...

Consider linear systems whose matrix and right-hand side vector depend affinelinearly on parameters varying within prescribed intervals. We present a C-XSC [9] implementation of a parametric fixed-point iteration method for the verified enclosure of the parametric solution set. Input data for the system have an entirely numerical representation by dense twodimensional matrices. Some specific fe...
