In this paper, A numerical study has been conducted to predict the hydrodynamic characteristics of the staggered ribbed backward facing step flow with inclined impinging jet. The impinging jet flow was inclined towards the main cross flow and the angle of inclination is ranged from  30 to  90 . The ribs were in staggered arrangement and aligned after the slot jet in normal direction to the ma...

The Lattice Boltzmann Method (LBM) with double populations is applied to solve the steady-state laminar natural convective heat transfer in a triangular cavity filled with water. The bottom wall is heated, the vertical wall is cooled, and the inclined wall is kept adiabatic. The buoyancy effect was modeled by applying the Boussinesq approximation to the momentum equation. The fluid velocity is ...

There is limited morphological data on the sex differences between the commonly used pelvic parameters. This study analysed the CT scans of 100 consecutive Caucasian patients, 61 males and 39 females, undergoing hip resurfacing arthroplasty surgery for hip osteoarthritis in one institution.There were no sex differences in femoral torsion/anteversion, femoral neck angle and acetabular inclinatio...

This paper explores the potential of solar energy generation in the area of The Hashemite University in Jordan (32.05_N, 36.06_E) by investigating the optimal inclination and azimuth angles of photovoltaic (PV) modules for every hour, day, month, and of the whole year. The object of this study is to maximize the annual energy production of PV systems by tracking the changes of sun's position in...

An important issue in zigzag pocket machining is to design a machining strategy such that the resulting tool path requires a minimum number of tool retraction motions. The minimization is further classified as either local or global. In a local minimization, the inclination of a zigzag path is given a priori, and the goal is to partition the planar region to be machined into a minimum number of...

We develop a new methodology to assess the streamwise inclination angles (SIAs) of wall-attached eddies populating logarithmic region with given wall-normal height. To remove influences originating from other scales on SIA estimated via two-point correlation, footprints targeted in vicinity wall and corresponding velocity fluctuations carried by them are isolated simultaneously, coupling spectr...

This document discusses a numerical analysis method for low thrust trajectory propagation known as the proximity quotient or Q-Law. The process uses a Lyapunov feedback control law developed by Petropoulos [1] to propagate trajectories of spacecraft by minimizing the user defined function at the target orbit. A simplified propagator is created from the core mechanics of this method in MATLAB an...

Experiments were conducted with PF-5052 liquid sprays impacting a 1.0 1.0 cm heated test surface at different inclination angles, flow rates, and subcoolings. Inclination angle had no noticeable effect on the single-phase or two-phase regions of the boiling curve. Maximum CHF was always achieved with the spray impinging normal to the test surface; increasing angle of inclination away from the n...

A general method of deprojecting two-dimensional images to reconstruct the three dimensional structure of the projected object – specifically X-ray, Sunyaev-Zel'dovich (SZ) and gravitational lensing maps of rich clusters of galaxies – assuming axial symmetry (Zaroubi et al. 1998), is considered. Here we test the applicability of the method for realistic, numerically simulated galaxy clusters, v...
