    There is reciprocating double stage oil free compressor. initially we want to simulate the cylinder in Ansys to get the Temperature gradient of the inner walls ( due to compression) as we have measured the temperature almost near the inner walls by drillling and making a hole in the cylinder by using thermo couple inside. so we want to simulate an cylinder in Ansys which will give the similar or near to equal temperature which we measured using a thermocouple .Working Principle:Its a double stage Reciprocating compressor right now we want to work only on the Low stage compressor. We have a reed valve on the cylinder which has 6 inlets for suction of Air with certain Density. Suction of Air happens when the compressor moves down. And after that there will movement of Piston in the Positive direction and there will be Compression. Once the Piston reached the TDC the outlet valve will open due to the pressure. Our main area of focus is to calculate the Temperature at the Inner walls where we have compression (i.e only equal to stoke Length of the compressor) And we are even interested to know the Temperature gradient through the cylindrical valves.This is only the starting stage of our project. If you can get a good accurate measurements. we can again offer you the third part of our work. In which we have again simulate the cylinder after Modifying the shape of the cylinder.Compressor Specifications:Ambient Temperature - 30cLow Pressure StageInlet Temperature - 60coutlet Temperature -110cPressure inlet - 0.95 barpressure outlet - 3.5 bar relativeAnd regarding the Price i dont how much fast is your computer so i cant predict how much time it will take for you to run this simulation. so i request you quote total price how much you will charge to develop the Model to calculate the inner wall temperature and Temperature Gradient for low pressure stage. And as i am a student i have to explain this to my professors how i have done this. so i request you to kindly record the video how you have done that and why you have chosen those option just while running on your system. So If you are Intrested to do this let me know i will send you all the CAD Files with perfect explanation and specifications

    Dear all.I hope you are well. I am attempting very basic thermal modelling using ANSYS. Its a very basic analysis but Its taking me very long to find my way. I will be very grateful if you could please point me in the right direction.I am a final year M Eng Mechanical Engineering student at the University of Bath and doing my final year project on Energy harvesting applications of Pyroelectric materials.M model is as follows:A ceramic (disk shaped)is placed under an IR lamp and heated using the radiaion from the lamp. The sides of the ceramic is open to ambient air and the ceramic itself is placed on a wooden block.From what I think, the ceramic is under the influence of radiation on the top surface, convection on the sides and top surface and conduction only at the bottom (contact with wood).I thought using an axis-symmetric model would be logical. Using PLANE 55 elements and making the area that is half the cross section.I am having trouble inputting radiation to the top surface. Do I need to add another element (SURF 151) which links radiation to PLANE 55 elements?Ill be very grateful for your help.

    It is for analysing the trajectory of how a dice falls for the purpose of improving throwing craps, i.e. exactly how you want it to land.- The phone will be placed half a meter from the dice thrower, with the camera shot facing the direction of the thrown dice.- Two dice will be thrown at the same time.- The dice will be 19mm red dice, with razor edges, like the ones used in regulation craps.- The dice are thrown at a target marked by a white (?) spot on a green felt surface 2 to 4 meters away from the thrower.- The camera will be recording the two dice dropping from above, onto the target spot.The application needs to calculate and return on the phone screen the results of the throw, within 1 second (the faster the better), the following specifications of the throw, accurate to 2.5%.(1) Speed of the dice upon impact on the felt table.(2) Angle of the motion of the dice upon impact of the felt table (should be average and around 45 degrees, ranging from 10 to 80)(3) The average drop location of the two dice compared with the target spot.(4) The difference in distance of the impact spots of the two dice.(5) The difference in time of the impact time of the two dice.(6) The face of the dice facing downwards upon impact.(7) How many corners of the dice touch the table before bouncing upwards, and it which order do the touch, and the timing difference for the contact.(8) The X, Y and Z axis spin speed in terms of revolutions per second (with positive and negative spins for each axis).(9) Trajectory analysis to work out the V angle from which the dice split away from each other as it moves away from the thrower.(10) Trajectory analysis to extrapolate the starting position of the dice (the starting position should be the two dice being held together touching each other in one hand), in particular, how high off the height of the felt table, was the dice released.Either Android or iPhone is usable, assume we are using specifications of iphone 5s and samsung s4. If more than one phone is required to do all of the above within the specifications, more apps can be written separately for two phones to cover the above 10 functions, but no more than three phones.Mechanical engineering is required to factor in the effects of backward spin and forward spin on the trajectory of the dice.
