(Texas A&M University. Turbomachinery Laboratories, 1996)Techniques for rotating stall verification and analysis of detrimental effects are described. Majority of dynamic pressure data presented herein are from centrifugal compressors, including one unit that required field ...
-
(Texas A&M University. Turbomachinery Laboratories, 2009)Vibration control is an important aspect of all pump design. It helps assure quiet operation and high reliability. Therefore, the design of pump components should avoid any dangerous resonances with excitation forces, such ...
-
(Texas A&M University. Turbomachinery Laboratories, 2008)Compression systems involving centrifugal compressors are designed and operated in a manner to eliminate or minimize the potential for compressor surge, which is a dynamic instability that is detrimental to the integrity ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1993)Some insight into the mechanism which generate lateral dynamic loads, and hence vibrations, on centrifugal pumps is presented in a general way, and the individual loads are explained and quantified. Without extensive use ...
-
(Texas A&M University. Turbomachinery Laboratories, 2000)Competitive marketplace pressures for higher quality products with consistent material properties at lower cost are changing the face of chemical process manufacturing facilities. More frequently today, critical equipment ...
-
(2012-10-19)Oil/gas and petrochemical plants are complicated and dynamic in nature. Dynamic characteristics include ageing of equipment/components, season changes, stochastic processes, operator response times, inspection and testing ...
-
(Mary Kay O'Connor Process Safety Center; Texas &M University. Libraries, 2017)The adjacent vessels may be impacted and/or destroyed by blast fragments in chemical industrial parks or plants, which could lead to the domino effects. Based on the analysis of common parameters of blast fragments including ...
