My Research topic is:Two dimensional modelling of sand production, using Finite volume to solve the governing equation and then use C++ to program.A C++ Visual code would be used to solve a 2Dimensional Navier stoke's equation in order to predict the critical drawdown pressure. I have been able to obtain the governing equation and discretise using finite volume.I have been given a C++ Visual code of 2D Full Navier stokes equation comprising of the Energy equation,Momentum and Pressure Equation which i have to solve for a flow in a pipe and obtain the Temperature,U and V velocity, temperature distribution and then the pressure distribution in the pipe. I wish to check the functionality of the code by making it obtain the required result with the various boundary conditions imposed(Top and Bottom -Insulated, Left-Dirichlet, Right-Convective).After solving the Navier stoke's equation for the above problem , i would also need to incorporate the code to determine the critical drawdown press...

I'm looking for an innovative chair back and armrest design. I'm creating a unique chair product and I need a backrest that can be height adjusted about 14" (7" higher and 7" lower from starting location.) The chair back is connected to a frame that also supports 2 arm rests (one on each side, obviously). The armrests also need to be height adjustable, approximately the same range as the backrest (about 14") but they need to be adjustable independently of the backrest. This is the general requirement, but I will send the winning proposals my drawings and complete details of the existing product so far so you can see what the constraints are, etc. I don't want to divulge too much yet, but I will provide the successful candidate(s) with complete information and everything you need. The goal is to find an easy solution to this problem, and one that isn't complicated to manufacture.

Parametric analysis of Solidworks flow simulation are to be carried-out using flow simulation API, the main idea is to edit already generated codes in VB 6.0 into VB.net or C++ (prefeably C++) , a plugin in terms of fluid codes (using codes already generated in C++ for navier-stokes momentum equation) should be embedded into the solidworks flow simulation environment), the VB 6 codes are able to do the following: 1. Change different impeller types used for the study 2. vary fluid height in the mixing vessel 3. Varying impeller rotational speed 4. Vary impeller distance from the bottom of the mixing vessel The plugin codes are written in C++, and its untended to be introduced into the mixing vessel as an external fluid and different results ar intended to be generated from the simulation that would determine which impeller gives better homogeneity and at what impeller distance this should be achieved.

Dear Bidders I will have 1 - 8 sets of plans a week, existing and proposed. And I need a contractor to use our excel calculator which will produce a quotation, you will need to go down the list of items in the calculator input the amount of material required and labour required to do the job. Its quite easy. You just need to know the amounts of materials required and the time to take to do the job. Each job will take a QS about an hour to do it. All prices are preset so you won't need to knowthe costs, just a mount of material and amount labour to do it. I am prepared to offer $25 per quote. There will be 1 - 8 quotes a week. I am based in the UK and am a director for my building company, the excel spreadsheet is copyright protected. Once you get in touch with me for a brief discussion I will then send you a sample quotation excel sheet you will be using. I have attached a sample set of plans which you would be using.

Items: -Multi functioning sports towel/shell idea -caribiner key chain idea with multifuntioning hooks -folding top (similar to a jacket in shape) that can fold into itself
