i Question A this section of questions is worth 30 marks Q1 Fill the missing words below using the most appropriate words from those provided. In almost all real-world, engineering fluid flow problems there are no [1] solutions and, therefore, alternative methods must be employed to obtain (2) solutions. Computational Fluid Dynamics (CFD) is a branch of fluid mechanics which utilises [3] techniques and (4) to solve fluid flow problems. In CFD, the equations that govern a problem are derived from the fundamental laws of physics-typically, conservation of [5) (often referred to as the [6] equation), conservation of momentum (Newton's [7] Law of Motion written for fluid flow), energy equation (derived from the (8) Law of Thermodynamics). For the solution process, the portion of [9] relevant to the problem is considered and is called the computational domain. Assuming the continuum hypothesis, the deputational domain is [10] into a computational mesh. On the faces of the computational domain, [11] are imposed. Appropriate numerical schemes and fluid flow models are selected, which convert the governing equations into a set of [12] equations. These equations are then solved on the computational mesh typically using [13] methods. For such methods, an [14] is required which is progressively updated until the calculated (15) is less than the specified tolerance at which point the solution is said to be numerically [16]. Other important criteria for determining simulation convergence include problem [17] (e.g. showing the velocity at a point of interest is constant, implying [18] conditions). In order to determine the robustness of the obtained solution, sensitivity analyses should be completed including a [19] analysis. Furthermore, the results should be (20), where possible, against available experimental data. END.
