    effect of coolig water temperature on temperature of all components in a water jacket cooled motor

    many thanks. Could you please eloboarte. I am new to CFD and thermals. I want to study how the density, heat capacity and thermal conductivity of the components and the temperature of the cooling water effects the temperatures of the machine. Please bear with me if i am asking a very basic things.

    effect of coolig water temperature on temperature of all components in a water jacket cooled motor

    Hi .. I am simulating a water jacket cooled induction motor. I solved the simulation for two cases case 1 : cooling water inlet temperature 30 degree Celsius. I this case the outlet water temperature is 31.4 degree Celsius. and the temperature at the area of...

    Shock mount selection procedure

    Exactly , I am designing it. But for designing it i have got few documents , But all of them explains the calculation method by considering the component to be isolated as a rigid mass. In my case the component is is a excitation panel (assume a box with number of sensitive electronic components...

    NX NASTRAN 10 IS SOLVING A PROBLEM WITHOUT ANY LOAD ..HOW IT IS POSSIBLE

    Hello i am using nx nastran 10.when i solve a linear static solution, with out any load , it is getting solved and giving zero displacement results which is correct with a zero load. But when i use nx 9 ,when there is no load in the linear static solution .when u click on solve,it will give a...

    nastran units for linear static runs (SOL101)

    What i believe and follow is consistency means if your model is in mm use mm, kg(or tonn) ,and newton(or milli newto or kilo newton) as units. if the model is in inches use inches , lbf. correct me if i am wrong .
